I think people characterize pedophilia as an absurd and dehumanized evil because they take comfort in its existence- they could never be that evil and thus don’t have to change themselves is a fantastic excuse for predatory practice. That is the myth of the predator that is sold.
Honestly people hating on this but this is about par for the course for adult animation these days. The cringe is not at heart from the Asian Americanism but fundamentally from the millenial adultingism.
