The good thing about fictional characters, u can say they're whatever age you want, the bad thing about fictional characters, your opposition can claim they look like whatever age they want too.
It's the kind of law that can be used to remove inconvenient artists from the picture. That is an interesting page, you can see what countries are most degenerate. like tonga. You're not allowed to own it but it's legal to produce it, that's suspicious as fuck.
But yeah, making fictional crimes illegal is such a waste of law enforcement resources, and bad for artistic freedom too. Like... Guts gets raped a bit as a kid in berserk, so wouldn't this make Berserk illegal in a lot of countries? I think Alucard had a similar situation too so hellsing as well
Fictional shit should be universally legal no matter what it is. By making certain disgusting things illegal in fiction, public awareness of those issues goes down as essentially nobody's allowed to really talk about it in real depth, even philosophically.
