My second question is: how on Earth did this shit ever get to be *legal* in Japan? Some people are *really* sick.
Revulsive as it is, I fail to see how making an ink drawing violates anyone's rights. The reason child pornography is illegal isn't because it's sick, it's because it can't be produced without sexually assaulting children, and sexually assaulting children is wrong (as is financially supporting such assaults).
Cartoons don't necessarily involve assault. They're just revolting.
