Even if they did cause violence in children, it's the soccer moms' faults for letting their 8 year olds play M rated games. The government is not your childrens' parents. Let me repeat that, soccer moms: THE GOVERNMENT IS NOT YOUR CHILDRENS' PARENTS. YOU ARE. Seriously people how about you stop waiting for the government to do away with everything that offends you and start doing this thing called parenting.
There has to be a scapegoat, and since just over 5% of videogames are rated M, That means ALL games are violent even if it's something like Klonoa! They're the perfect thing to blame because if you play them, you automatically become a ticking timebomb... don't you know how this type of logic works?
