I have no doubt in my mind that violent video games do contribute somewhat to the violence problem we have here in America. The sole cause, or even a major root cause? Not even remotely close.
Each "side" of the debate is just posturing. Jack's side is theyre all evil, the other side is the cause no harm, and the truth lies somewhere in the middle.
Saying "it's all up to the parents" is a total cop out. It's a nearly completely impenetrable point, because refuting it requires more honesty than anyone in that situation is willing to give. The truth being, with a few EXTREMELY RARE exceptions, parents have a very distorted view of what we actually watched or did as kids. If we wanted to play violent video games, or beat each other up, or blow stuff up, or curse, smoke, do drugs, drink etc......we just did it when they weren't looking, and convinced our parents we didn't. Nowadays, its impossible to avoid violence, bad language, or sexual material unless you completely shut yourself out from the world. As soon as a kid gets an email address, the spam will start flowing, he will "confirm being 18", and krauts are going to get shot.
The main point is, which Adam made, is that there are more important things for us to worry about when it comes to dealing with the problems our kids have. Instead of trying to ban a game called "Bully" (which I've never even heard of), maybe they should do something about actual bullying.
If anything, I'd like to see less violence in games, that way there's one less gimmick, and more incentive to make a better game, rather than just oooooh gibs!
