I am as well. The system self-censors itself well enough without the government stepping in. The ESRB does a great job of rating games for content, and the console manufacturers don't even allow games with AO ratings to be published on their systems. Something like Rapelay would never see the light of day on a console.
As for the PC, it was released to the Japanese market back in 2006. No one cared, no one cared, and everyone continued to not care for almost three years until the western media heard about it and was outraged on the behalf of parents everywhere in spring of 2009. The game was discontinued at that time.
Now it's a year later, and CNN is apparently only just hearing about this old discontinued PC rape game, and everyone is now very worried about how easy it will be for children to get their hands on a discontinued game that was never sold in the States that they'd never heard of until CNN did a story on it.
Kids aren't playing these Japanese rape games. If they're playing anything, it's GTA, and the answer isn't censorship. It's parents actually paying attention to what their kids are playing and not buying them games where the title is a felony.
Here's the co-author of Grand Theft Childhood talking to CNN about it. I can only assume that CNN didn't do any research and assumed from the title of her book that she'd be only too eager to agree with their bullshit.
