Hardly any, I enjoy everything well written, from furry to vore, shota and rape, I can eat everything as long as it doesn't go out of its way to defend these behaviors in real life (propaganda), I've only seen this once, which is the only comic here that got me mad not for being badly written but for being disgusting.
I only got really mad at this one adult X preteen teacher x student where the classmate who finds it wrong because of their age gap is presented as the villain and the kid's dad is supportive and says it shouldn't be treated as a bad thing cause (referring to the age gap).
That's genuinely fucked up, I don't mind shota, but that one was making a point of advocating in favor of pedophilia and putting anyone who goes against it as a villainous person who want to destroy pure love. Like, that's insane.
Everything else is at most meh, most of the time is poor writing (alphas not being expected to marry omegas make no sense) or lack of understanding of what discourse construction.
Like profundis has some early discourse and writing issues that I believe was an editorial failure (later on, the rush and all, I also think that's editorial. But wtv), I believe the sex scenes were intentionally uncomfortable in the characters actions and speeches, to show it's wrong, but it was also drawn in a sexually stimulating way, instead of as something horrifying.
While I don't mind the rape in smut being treated as sexy (you will find me in the worst comics if it's good, a well made mindbreak is soooo fun!), you gotta pick a side. Is it supposed to be realistic or sexy? Cause you can't have both without sending out a certain message.
The author hasn't shown anything discursively to make me believe they are like that shotacon, that they were intentionally selling an idea pro-irl-crime, so I can only believe it was bad editorial work, who didn't understand those early scenes should either tone down the bad vibes or the sexy portrayal of the rape.
Like, jinx has rape drawn as negative and sexy, but the negative part of it is toned down enough that or works, it's smut and it's fine. The pearl boy sequel also does an amazing work because we have rape between the main couple, which is presented in a way that can be dismissed, while rape from the patrons that is entirely made to be disgusting and repulsive for the audience.
I really dislike bad writing and people who don't understand their own medium. Panel construction and the feeling your drawing is meant to evoque will change the final message. But yeah, that abo trope is not that deep, it's just a very dumb poor writing choice that is repeated ad infinitum.

If you're not gonna read all, don't answer. I got mad at the lack of verisimilitude in the world building of ABO societies. Don't say "it's fiction/fantasy, it doesn't need to make sense" except it does! If I establish that a donkey and a dragon can have halflings, I either make it so that this is a power of the dragon or that every other species can. I can't have the donkey and a lizard breaking up because they can't have kids for being interspecies if I've shown the lizard having halflings with a horse, yk? There has to be some intraworld rules.
This is me, ranting, because the whole "you are an alpha, you should be with a female alpha, why would you even want an omega like me" sounds the same as "you are a man, you should be with a trans man who still has his womb, why would you even want a woman like me".
It never made sense to me. Even though you are biologically engineered to copulate and have childrens and be mates for life and being with anything but each other would be considered unnatural in the cycle of life, that's still a common trope in ABOs.
Your heat triggers their rut, your pheromones attract each other, while same-sex pheromones are repulsive, marks are for life and only alphas can mark and only omegas can be marked.
Now, how the FUCK does that even work? Alphas repulsed each other, can't mark each other, can't satisfy each other's ruts, are harder to impregnate. If we are thinking of lineage, and we want to guarantee many possible successors, alpha x alpha would have a very hard time producing a baby. Why would a female alpha be willing to be impregnated? By nature, that goes against how she is wired, her pheromones are pushing the other alpha away, she's not in mating mode, they'd likely fight for dominance and she's an alpha, if she won the fight, she'd fuck her husband, bye bye babies! (rape can be used for dominance, cock going full mast is used for intimidation and to fight off invading males, etc, animal behavior).
Why would her powerful family see this powerful alpha and think, yeah, she should go and be submissive to ANOTHER alpha who will take over our family's business and erase out surname, even though they are both alphas and we could get her a pretty passive omega to pump out pups?
Most of all, no guarantees for loyalty, unless you are homosexual and attracted to the same secondary sex, you don't actually like alphas, you are both going to go fuck some omegas (all those alpha X omega stories always goes "I feel nothing for that alpha" like, buddy, you are attracted to the opposite sex, you are straight, you want an omega, of course you don't want another alpha). Now you have a shit ton of bastards because the chances of an alpha imoregnating an omega if they mate is always 100% if they don't use protection and if you go into rut/heat your instincts will force you to throw away the protection.
(always ridiculous how they can't avoid raping but can always put a condom. You don't get the urge to merely have sex. Your instinct is to MATE, to PROCREATE, you want to pour your seed, until that womb is fertilized you won't stop! And omegas are designed to be better at being fertilized than a beta woman, and alphas are perfect fertilizers. So much semen, such a fertile womb, all those eggs being impregnated. Every rape scene in abo should, by the concept of the abo universe, end in pregnancy if it isn't followed by plan b)
Like, socially, it doesn't make sense that people would put alpha men and women together.
In ABO, where the traits are a given, normal for society and such, they clearly take precedence over dick/vagina dichotomy. Some still include misogyny (for some unknown unexplained ahistorical possibly anachronical reason if the secondary traits have existed for that long), but in general, we know that society divides male and female, of any species, including plants, as the one who inseminate and the one who makes/hold the fertilized eggs.
So for the sake of this discussion, I divided the population into inseminable (female betas and alphas and all omegas) and fertilizers (male betas and omegas, and all alphas).
Now, I really don't get it when, in ABO comics, there's always this "you are an alpha, you should be with another alpha, not an omega like me". What is that all about? "but society is prejudiced against omegas" now, talk to me, what does society views omegas worth as? Breeding. Much like our society views women. And yet, our society tell you NOT to be with another man because he cannot procreate.
I thought "are the secondary sexes being treated like races then?" because if alphas were white people and omegas people of color, then it'd make sense, racist society doesn't want a white fertilizer mingling with an inseminable poc.
But that also doesn't work not only because it forgets betas (while I admit, they are treated as if a whole other species in most omega x alpha works), but because we still have racial markers in ABO world.
More than anything, secondary sexes are actually treated like nobility ranks. An alpha marrying an omega is treated as the same of a king marrying a very poor commoner (or even a slave). And the thing is, it just doesn't make any sense. Because is not a social construction made out of sheer belief, it is a social construction made out of biology. Being based on biology doesn't mean that it is right, but it does explain how that train of thought organizes itself.
The arguments made by sexists and homophobes and transphobes and racists, they all try really really hard to hold themselves through biology qnd that shapes not only their arguments but their prejudice (is not that women shouldn't work. It's that women should work with crafts because their hands are smaller. And the whole race intersectionality because black women are expected to work the same load as black men, and so they make up racist science to justify that, and it shapes the whole narrative and what new bullshit they come with).
What I'm trying to say is, the whole nobility like treatment of ABO would not exist if the prejudice is biologically based on their roles in the continuity of the species. And that also forces me to talk about one thing that's often forgotten, put out of the equation: misogyny.
I see misogyny in two ways when we talk about alpha beta omega:
First, I think if the ABO setting is written as something relatively new, with little spread (even if popularize enough for everyone to know what it is and take the test), and written in a way that the common person, a beta, hardly sees alpha/omegas in their daily life, then yes, the secondary sex appeared probably one or two centuries ago, it's still like a novelty, and as such it was just added to a hierarchy. Then why are alpha women above beta women? How was this conclusion reached. I get that omega men are seen as lesser because they are too close to women, but why would they rank higher than an omega woman? And if we go for the whole "society would view him as an abomination" why are alpha omegas above betas and not in the same level as omega men?
(and here we would need to get into the conversation of intersectionality and how intersex and trans man compare to intersex and trans women in the social hierarchy, but I think it's safe to say that since ABO are secondary sexes, you are born knowing you have a vagina or a dick, so the idea of a trans man being read as a woman by transphobes and suffering both transphobia and misogyny is not equivalent to the omega man experience, as he would never be read as a woman, but he'd be read as lesser than any other man)
Second, if you see enough alphas and omegas and people are not surprised by seeing one in the wild, if there's no "omg, I've never seen a male omega before" (they might get surprised that that one person is an omega, but not at seeing an omega), if their section boss is an alpha, if their school most popular kid is an alpha, and the school beauty is an omega (BTW, what's up with that? Omegas are supposed to be pretty af, why do we never see people shipping the hot alpha with literally the prettiest omega, but instead with another alpha? Why everyone assume ppl are into a/a? Is everyone a fujo in this universe??).
If THAT is your universe, then I'm sure society has overcome the vagina/dick dichotomy. Male omegas have cloaca instead of anus, female alphas have Retractable dick instead of a clit, so, I mean, we are all clearly used to this, and the alpha above beta above omega social hierarchy makes sense.
So we go back. WHY IS EVERYONE EXPECTING EVERY ALPHA TO BW GAY AND MARRY ANOTHER ALPHA?????? If that's the rule, why aren't male omegas also expected to marry female omegas???? Why everytime we see the whole "you're an alpha, you should be with another alpha" we never see omega X omega couples? Why the omega's exes are never other omegas? Why is alpha X alpha the socially expected if alphas, the ruling class, would feel SICK at the presence of another alpha pheromone? And would crave omegas? I get it when omegas are treated as slaves or commodities, housewives and birthing tools, it makes sense (not saying it's right, for the ones who lack reading comprehension), but when alphas are expected to not have an omega? What about polygamy? If alphas are expected to only marry alphas, wouldn't in modern society polygamy have been made acceptable? If omegas are treated like pre-medieval women amongst skyscrapers, then you could walk around the Tokyo tower with your concubine-like secondary sex partner?
Alphas are the ruling class! They would NOT get themselves the short end of the stick? Most sexists alphas don't hate omegas, they hate the idea of their omegas showing skin, working, having friends, not fucking when they want. They don't want distance from omegas, they want ownership, it's instinctual. Even the most incel-like thinkers amongst alphas would still be like "these disgusting bitches are only worth for fuck, we should all be given a free, disposable omega, trained by the government, to relief our rut and impregnate".
It's just… I love when people go full fantasy and homophobes just don't exist, I have a blast, I love public relationships. But it's not that they don't exist, is that in every a/o ABO everyone is a heterophobe.
I get that for betas because really, they can't handle ruts/heats nor satisfy their alpha or omega partners and have no pheromone (this is so funny, like "yeah, a man can't self lubricate, he gets sick if you cum inside and they don't have tits, so it makes sense you would expect them not to fuck each other" like, that's exactly what the "betas should be with betas only" argument sounds like, help, wtf). BUT FOR ALPHA/OMEGA PAIRINGS?
Anyways. I genuinely don't thing society would have any issues with any ABO combination IF they can produce babies. Because, that's kinda the big thing people use to justify having issues with gay couples.
They'd look iffy (but in the same way ppl look iffy at a beautiful man with an ugly woman, yk?) at:
- an alpha choosing a beta woman
- an omega choosing a beta man
I do think they'd be normal but in a "how do they make it work" way (like how you look at people who are clearly very different and you think oh I'd never, like a poacher and a member of PETA dating? /j more like the alt greenpunk anarchist and the techy preppy crypto investor) towards:
- alpha man and alpha woman
- omega man with omega woman
They'd definitely be harsher, but look more like it's and exotic thing at:
- alpha woman with alpha woman
- omega man with omega man
I think they'd have a real problem with combinations who can't procreate at all:
- beta woman with omega woman
- beta man with alpha man
- omega woman with omega woman
- alpha man with alpha man.
That's just what would make more sense than the whole omega "you should be with another Allah, why would you — an alpha, biologically made to want me —, want me?" speech we so often see.
