Okay, so you will obviously dismiss any studies as "guess-work" and cling to your own observation of a few "people" who play these games. I guess the discussion ends right there because you won't bother to listen to anyone but yourself.

You are right, people don't NEED anything to cause violent behavior. No one ever claimed that video games were the cause of violence. But there are OTHER studies in addition to the ones I mentioned that show a rise in aggression from people who play these games.   This does not mean that everyone who plays will go out and shoot up the neighborhood, but it is not a healthy pastime.   You can kid yourself into thinking it is alright, but it is not alright for everyone. Most people can have a few beers without any problems, but for some they become monsters after their first. Violent video games are not HELPING to resolve any of the problems that cause violent behavior. They are not doing anything positive, except making money for someone who is appealing to base instincts and preying on succeptible people.

Whatever you do is your own business. I am not trying to stop anyone from playing these games. You can spend your day in front of a gaming console, typing on the internet, becoming a master of your own domain, or writing manifestos from a tar paper shack. Your business. If you ask for an opinion, you should have the courtesy of listening to it and not dismissing it simply because you have your own opinion.
