He's not really wrong though. His language is annoying, but it's a fair point. Most gamers I see talking about this issue sound just like gun hobbyists: defending their hobby to extremes because they're biased.
Media effects us tremendously. Nothing wrong with examining games' effect on kids and perhaps making it harder for them to play violent ones.
I absolutely agree that there is nothing wrong with examining the situation. In fact, I encourage it because I am certain that it will prove what multiple legitimate studies have already proven: games do not increase actual violence in any measurable or significant way. They do increase aggression in individuals, as does any competitive activity such as sports, but aggression does not automatically equal violent acts.
What I disagree with is that any group, especially a group so intimately involved with the topic at hand, should be excluded from this discussion. Why is Yee's obvious bias about games more valid than gamers' bias?
