Another reason they might not fully hate him is probably because the omegas are high in socioeconomic class but underprivileged as omegas, so their approach to personal politics is the real life equivalent of liberal feminism and moral politics. Kinda the same as "women should be billionaires too!", instead of a more grounded approach of "there shouldnt be billionaires at all".
Even if an omega has internalized sexist ideas the rest take that self hatred and harmfulness as a way of "protesting in existence". They dont seem to catch on that his queerness (cuz he likes the same secondary gender, omegas) and his genderqueerness (hes not exactly comfortable with his own existence as an omega), may make him the same as any other underprivileged person, but he was socialised as an alpha so he wont be able to start thinking like an omega overnight.
I can talk on and on about him man i love this mess of a character.
I was also initially confused if he was truly genderqueer in any sense or not but knowing the risks of a complete organ removal surgery, he wouldnt just do it to protect his social position as an alpha, it can also be partially due to major dysphoria regarding how his body suddenly started functioning after a second puberty. Thus him going for gender affirming care and solidifying my stance on him being transmasc/ transalpha(?) in some manner.
This story to me is so important cuz it goes against the entire heteronormative story setup that majority of omegaverse love stories fall into. The author using it as a way to comment on class differences, attitudes toward gender and sexuality and taking such a grounded approach to the idea of a 2nd gender affecting a person's life rather than simply being a plot device for a romance. All of his relationships with his partners also give u insight on how different dynamics in omega x omega relationships might work out. I do wish more people would write on omega x omega dynamics its so underexplored
I feel the same way, this story gives me chills because im genuinely so invested in his life. And i cant hate him.
I also love what you said about heteronormative in omegaverse, for me this genre its rlly fascinating and the way asada nemui explores it its wonderful.
The only thing that bothers me is that, there’s some topics i wished were explored more, like the MC assaults, etc. But i feel like manga / yaoi tends to have quicker storylines.

Takatora is such an interesting character to me because of the author's portrayal of him. His intersectionality is so fascinating because you have an omega raised as an alpha so, he wasn't raised with the same restrictions that the other omegas in class were, which technically makes him kinda progressive. However, he still views omegas as inferior and sees himself as the exception because he’s sexist. But I can see why the omegas in class can't fully hate him, despite Takatora himself being a shitty person, because there is always something to admire in someone who doesn't let their role define them, even if the role Takatora is following is stereotypically an alpha's role.
I love Takatora so much and the terrible choices he makes throughout his life. #freetheomegasfromthismanimcrying
