I mean it is just a fact media influences what is seen as acceptable or understandable in society, and can normalise certain behaviours. Like for example the common presentation of women as sexual objects, which helps to normalise negative attitudes towards them and ppl who would treat them as such. You don't have to be personally influenced by it to recognise the potential harm. In fact only ppl who aren't influenced by it are able to stand back and be more objective about whether it's right or not. I don't understand the argument ppl try make that all entertainment and media should somehow be separated entirely from morality, and a moral argument is supposedly less valid or worthy because of that. It sounds like it makes sense at a surface level sure but thinking about it for more than two seconds what even would be the argument for that. It's a lot of words disguised under a guise of liberty or freedom without recognising ppl's liberties are restricted all the time everywhere to varying degrees depending on the overall potential impact or harm the state sees a specific act as having. I mean personally i don't really care if people wanna read incest, i don't think this act specifically is going to be normalised just because of manga like this, but it makes no sense to get angry at people who are upset. At least not using this argument anyway. It would be a slightly more logical and unemotional argument even to argue there's little moral argument against incest but no one on the side of reading about it wants to try that angle for whatever reason
-you spout a whole lot of big words but nothing you've wrote has any scientific proof behind it. If you cant differentiate reality from fiction that is a developmental issue w you. The ppl that you think have been "affected by fiction" have ALREADY been pedophiles, predators, incestuous or violent, not bcuz of fiction so get it right
Wait so is your point that presentations of media - not just games, but books or movies - of say idk certain races or nationalities or genders etc as bad has literally no impact on that society's perceptions of said group?? Because that's like the extension of that logic, otherwise where are you drawing the line. There's literally studies on this, humans as a whole are very easily influenced by things like this. You don't have to take my word for it, you can just look it up and no i literally said word for word i don't think reading this would make you want to endorse it, i just said the argument that morality has no place in manga is dumb. If "amoral" media had no impact, why do we ban certain books?? No normal person would object to the banning of books as an idea bc "only idiots would let themselves get influenced by smth clearly bad, if you're so easily influenced then don't read it", but you can object to the substantive content of what is being banned. Basically you can't object to ppl having hang ups about incest manga based on their ethics but you could object to them thinking it is unethical in the first place. But for obvious reasons no one's gonna do that. That's why im just saying the argument morals have no place in manga doesn't make any sense
You sound much more pressed. First of all, I wasn’t even talking to you. I was asking for HIS opinion, not yours, lmao. Bro really thinks everyone wants to hear what he has to say. Maybe learn how to read first and develop some social awareness before inserting yourself into a conversation that has absolutely nothing to do with you. Not every conversation is an invitation for you to butt in. Learn when to speak and when to mind your own business. Read jinx or something lol.

Fiction doesn't have to be moralizing or activist, nor do the characters need to teach you the difference between right and wrong; it’s up to you to have enough critical thinking to discern that what you’re reading has no real impact on your fucking reality. If the mere depiction of evil tempts you to imitate it, then you should rethink your own values; perhaps your morality relies entirely on a fiction to be shaped (...which depends on you as an individual—how easily influenced you are).
Fiction can be presented through various narratives that—depending on the author's intent—lend themselves to analysis, questioning, and even debate... but if you are impressionable enough to want to imitate a caricatured version of fiction and place it on the same level as damn reality, then you don't possess much critical thinking.
