I'm still curious about one thing, what games do promote sexual violence? I know about Rapelay (who doesn't?), and I presume there's others like that from Japan, But I can't say I've played anything in the more core western market like that, which is where something really has to be if you want to make an argument against it. Otherwise it's just fringe media for already crazy people.
There's games with sexist sexual content like Duke Nukem, and games with sex, like mass effect, Fahrenheit and GTA. But that's either for adolescent macho chauvinism, or part of building character relationships, so I'm just not seeing any connection.
Also, with the post columbine polls, were they before or after FOX started announcing that doom caused the shootings?
