Lol. I just hope no kids are watching Matt Dufty, they'll turn out French.
In seriousness though, it's not that they learn it's OK to rape people. It's more about shaping attitudes. It's always been clear that our heroes and our role models have an influence on our character, that's all. JDB won't be teaching kids to rape any more than playing GTA teaches them to run over prostitutes, it's smaller and more subtle than that.
If anyone is a psychiatrist or something I'm sure they could explain it better than me
