I thought this debate was over in the USA already. I remember there was much noise and commotion generated a year ago or so, but if I understood correctly, drawn material was excluded from the tightened laws.

This sort of censorship is always dangerous. There are no victims at all, unlike with real child pornography, so it's not even protecting anybody. The old saying says that if you offer the devil a finger he will claim the whole hand. That's what would happen here, and before long series like Shakugan no Shana would be banned as well.
