Violent games do not incite violence in those that play them; anyone who thinks otherwise is an ignorant fool. Violent games provide an outlet for the natural aggression inborn in everything. The 70's and 80's are a testiment to that; when kids were exposed to nothing but the happiness of The Smurfs and other shows like them the levels of violence rose drastically. However, in the 90's, when shows like Power Rangers became popular, violent outbreaks began to drop and have continued to drop ever since.
Everyone and everything on this planet is naturally violent, video games and movies profide us with a means of using this aggression in a harmless fashion.
