Just look at animemes banning the use of tr*p. Of course not every anime is misogynist but... there’s kinda a lot. And I think there’s a lot of blatant misogyny that is definitely noticed, and people who watch those scenes know it’s bad, but if you keep watching that shit over and over, even if you know it’s bad, it just get burned into your brain. But more importantly, a lot of anime just treats women as a whole differently than the male characters. Their drawn slightly differently, they act slightly differently, and they continue to be treated as objects, albeit in more subtle ways. On their own or in a bubble these grievances wouldn’t be a big deal, but it does add up. Idk, shit just sucks and it makes it hard to get into shows I would really like otherwise...
There’s a lot of people between those two extreme though.
Least in my experience there plenty of people who like anime but don’t really give much of a fuck about Japanese culture beyond maybe also liking sushi or whatever. Honestly I just enjoy it because it’s more open to exploring weird story concepts than a lot of western media, the fact it’s from japan doesn’t mean jack shit to me.
