Are you seriously surprised? /co/ is an anonymous image board, so the majority of posters come here because they can openly brag about their more taboo and fucked up tendencies. It's why you see so much blatant racism and pedophilia.
Plus, every animated series with a female lead seems to mainly get attention because of horny freaks wanting to fuck the little girls. I remember the threads leading up to Amphibia's premiere used to be super comfy with some genuinely interesting discussion, but it's all gone to shit since then. Same for any threads for the shows in pic related.
Pedos really are the worst.
