>>7280843Lolita's sex scenes aren't as graphic as you seem to think. The descriptions can be rather vague, and most of it happens offscreen.
>>7280815Actually, older guys trying to seduce young girls is a pretty popular element in shoujo manga. I think it's more about the reader sympathising with the young character than that character's gender. A josei shota manga in which elder women try to seduce a shota would be equally inappropriate to a men-seduce-loli manga.
The reader is supposed to put themselves in the shoes of the object of the pedophile's desires, not the subject that feels those desires and possibly acts on them. I think that's where most people see the line between appropriate and inappropriate.
