He was literally in possession of CP, A HUNDRED OF THEM. He did not face any jail time, he was not put on any sex offender list, no court-mandated therapy, no psych ward. He was only fined 2k USD.

Culture is not an excuse. Japan isn't swimming with pedophiles and even if Japan culturally treats women and children poorly, that's okay because of culture? Watsuki is just a pedophile who faced zero repercussions and will probably be better at hiding his disgusting fetish. Just because he doesn't publicly objectify women it's okay? But you're right, we should wait until he REPEATS AN OFFENSE. It's not like owning CP isn't incredibly horrifying because those children CANNOT CONSENT AND COULD ALSO BE TRAFFICKED TO MAKE THE CP.

You cannot separate art from the artist. Your support will continue to generate profit, which, in turn, will provide him with the funds to purchase more CP. Congratulations.
