Lolicon is specifically art/porn of underage girls. Not just a few years underage, like 15 or 16 years old where they have developed secondary sex characteristics and are sexually mature to some extent. I mean very explicitly underage, pubescent/prepubescent girls that haven't matured to the point of having secondary sex characteristics. Quit muddying the waters by calling things loli when they fucking aren't.
And for the record, yes, lolicons are pedophiles. Back when the lolicon general started on /ic/ I went into those threads to troll lolishitters, and there were (and are) people drawing loli in a semi-realistic style as well as anime shit. Most damning of all, there was an actual pedophile on the thread who was saying vague shit to the effect that there was nothing wrong with being a pedophile, and he ducked out pretty quick after I called him out and asked him to explain himself. Then some faggots dogpiled me trying to cover up for that piece of shit, after that the whole thread became a flame war and I basically crashed the damn thing with no survivors.
So yeah, lolicons are pedos. They're just really good at denying it.
