Of the many contributing causes to American violence, I don't think video games are an especially high priority. But neither do I think the possibility can be ignored. These attrocities have to end, and we should all be willing to consider all potential causes. I love video games, but if a thorough and valid scientific inquiry shows a causal or aggravating relationship between violent video games and real-world, violence, then I would be willing to accept restrictions on sales to minors.
I will be insistent that the NRA and other pro-gun groups contribute constructively to the debate and possible solutions, and be willing to compromise, and gamers need to be part of the conversation too.
By all means, let's not over react, and knee-jerk reactions are not helpful, on either side of the question. But there are no sacred cows.
Yes, there is a sacred cow. It's called Freedom of Speech.
