I don't think it should be banned. It's certainly fucked up, but I don't think it's something we should consider taking seriously or even the notion of people taking it seriously over here in the States, or Canada, or Europe. It's not something that 99.9% of the population of any country in the west would find remotely interesting.

If anything, I think the only thing this represents is a certain inherently creepy aspect of Japanese culture that is utterly rape-obsessed. It's fucked up, but I seriously think it's a cultural thing.
