Both are faggots, X is a pedophile not because of the relationship but because he admitted to being into loliniggery. He was also completely aware he was being degenerate proven by his behavior here since he is familiar with the nature of child abuse. Since most evidence is kinda vague I don't know yet if it would legally constitute as grooming (but he definitely tried to groom him into feminization) but it still morally wrong at least from this perspective since x was the most aware in this situation.
And requesting sexual imagery of someone who's underage is illegal even if they're the same age btw. Might not be morally wrong if they're both unaware but X knows damn well what applied to CSAM laws proven by his post history and his deflection in the appeal.
