True, but I don't think videogames are being singled out just because they desensitize people, particularly the younger generation, to violence. I think they are singled out because many games have you actively participating in violent acts that, because it is a videogame, have no consequences.
You really can't compare seeing violence on the 6 o'clock news and playing a videogame that requires you to kill other players. It is important for us to be educated about the various acts of violence that go on around the world in order to come up with solutions on how to prevent these situations in the future. The knowledge gained by seeing what is going on in our own neighbourhood or in another part of the world is incredibly important to decision making that involves bettering those communities. The world can be a violent place, but ignoring that fact is not going to make it any less violent.
Videogames are the opposite. We can make a virtual world any kind of world we want, so if we don't want to live in a violent world, then why do we want to play in one? Violence in videogames can be easily avoided, unlike violence in real life.
So once again, I don't think the comparison stands. I agree that both violent videogames and violent news reels contribute to the desensitization of violence in a person. But avoiding the issues surrounding violent videogames, by pointing at violence in news media, is just as bad as avoiding the issues surrounding teenagers prone to aggressive behavior by pointing at violent videogames.
