I support strict content regulation of violent videogames, but I highly doubt videogames universally make people violent.
Who spends the most time immersed in a given violent videogame? The game developers of course. If videogames universally train people to become violent, then the behavior of all videogame developers would have to most clearly support this claim. Not every violent game developer can aim a real gun properly, or feel indifferent to injuries on real people. Other factors influence the suspectability of a person to commit a violent act, and violent videogames are just one of a vast ocean of potential influencing factors.
