They're clearly attracted to the child like features of the drawing

Which features would those be?

The eyes the size of a grown man's fist? The noses that are so upturned as to be horizontal, and have no nostrils? The lipless mouths? The necks as thin as wrists?

The features are not even human-like, let alone child like.

Anime characters are not humans, and the ones drawn to be cute do not even resemble humans.

Would you say this same shit if someone jacking off to some American style drawing of a child

Nobody jacks off to western art because it's too realistic and therefore unfappable. Which proves my point.
