The funny thing is that all these hysterical news reports about things that supposedly influence kids--be it music, video games, movies, TV, etc.--fail to ask what the kids' home life is like. Also, some people are just born fucked up and there's no rhyme or reason to it.
I'm just glad I played so much Quake all those years ago, because it sure helped me learn how to use firearms. Anyone who's ever fired a real gun knows that it's just as simple as moving a mouse around and press Control, right??
