I sent an email to the author. Went like this:
Dear Mr. Byron,
I have played and enjoyed Grand Theft Auto: Vice City. I have never killed anyone, nor have I ever struck anyone in anger. People enjoy different forms of entertainment, and while video game violence may not be your bag, it certainly is enjoyed by many other adults. The fact that children can buy and be influenced by games of this type only stands as testament to the horrible parenting skills of many Americans. Instead of sensationalizing the fact that these games are made, perhaps you should draw attention to the fact that many parents irresponsibly allow their children access to this type of entertainment
