What's the Moral Debate About Hentai?

There was just this huge moral debate in Japan in Japan for so long about it. There's ways to get hentai of underage girls because it's fake porn, but still you can't draw them. I don't know if it's legal or illegal, but you can get it easily from what I could find. And then there was also the debate of like maybe he genuinely identifies as a vampire. Like maybe he feels like a vampire. Yeah, that's freaking scary.
