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...
While there aren't many actively good and feminist anime (It's mostly just Utena), anime as a whole isn't particularly worse towards women than western media it's just a lot more immediately horny than other forms of misogyny. And the western fanbase of anime were mostly misogynistic before watching anime, it's not the anime itself that reinforces those beliefs, it's the communities surrounding it. As proven by there being plenty of anime fans who aren't awful who mostly avoid major anime communities.
