You may actually be an idiot.
I watched all sorts of stuff as a child and didn't repeat it. I mean forget I played GTA and I didn't grow up beating people with a carrot and stealing cars.
violent games are outlets for people with already existing problems, they do not however cause them
in essence his argument is true to a point, you can't seriously say playing games glorifying killing won't have an effect on a childs behavior, but only in certain circumstances will video games actually result in violence irl
