If I recall correctly it has been proven that violent games do not affect young adults in negative way unless they are already mentally disturbed. There are thousands of movies that depict killing and sexual violence and nobody talks about it anymore. I think just like Gabe Newell said that videos games are more powerful medium than movies because they give you control over your character and you can shape the story how you like. That's what is bothering those "human rights" warriors. They are against games because they are such a powerful art tool.
