1. Don't worry about what I'm playing
2. If you don't like it, don't buy it
3. If you're stupid enough to buy a kid an M rated game, you have bigger problems than violence in video games
4. This is entertainment targeted for specific audiences, just like the movies; treat it that way
5. Don't tell me there are no good games for kids. There's a ton of games in mutiple genres for all ages; if you're spending $30-$60 on a game, you might want to do a little research first.
