I'm on both sides. As an artistic person and person interested in art, plenty of it edgy, I feel very similar to the way Cobra does. That said, I can't agree that there should never be any rules. The problem in making them has already been detailed by Cobra, and it's a depressing topic to me on all fronts. It's been said that a country has to step in and start policing its own people when the people stop policing themselves, and that's what I see in the youth of America today. It has nothing to do with being free to express themselves, it has to do with indulging in fucking degeneracy just for the sake of indulging in it. There's so much filth out there it disgusts me. But again... where do you draw the line? Who makes that call? What rights should artists be afforded when doing work that falls out of the "normal" range?
But yeah, I don't find anything Wind's posted particularly interesting or strange. Frankly, there's plenty of similar stuff in America. Violence and sex go together, and war machines/giant robots/fantasy monsters are often sexualized in all parts of the world. I don't deny that the Japanese have some significant problems when it comes to perversion (and I would say that yes, they're problems, not simply cultural differences), but that doesn't extend to every last thing. They also do some incredibly beautiful stuff that's unique to their country.
