I think this site in particular picked up on anti-anime sentiments as a reaction to anime fans being predominantly reactionary themselves. It's something I see in anime subreddits (and my experience in irl meetups) and that goes hand in hand with loli fetishisation.

But I see a lot of love for anime here myself, so I wouldn't go so far as to call it "lowkey kinda racist". Just gotta keep this website :hentai-free:
