He's right in a lot of ways. He's right in the same ways that Atkinson is right (and trust me, they're right about SOME of their ideas).
What they're right about is, kids shouldn't be playing Grand Theft Auto.. Or RapeLay (seriously atkinson? I digress..) They're also right that most parents ignore the labels instead choosing to sate their children's screams. It's something they can control in a world of things that make their kids cry for things.
What they're very wrong about is how to deal with the situation.. You don't do it by parenting for the children (especially if it means parenting for those of us that are of age).. The games industry doesn't want Mature games in the hands of kids. Talking about kids in relation to Mature games shouldn't even be a conversation. You can talk about parents though.
I think another thing they're overlooking is that MAYBE, just MAYBE, those parents know what they're doing with their kids. If they're going into it educated, and know what Rated M for Mature means, and still choose to buy it for their kids, then that's really none of their business. Unless there is ever proof that buying M Rated games for your kids is a type of Child Abuse (read: It's not), then there's nothing you can do.
The best you can do is educate parents, and we as gamers need to take some of that responsibility onto ourselves. If you ever see a parent struggling in the game section of the store, approach them kindly, and give them a hand. If you ever see a parent with a kid begging for an M rated game, kindly approach them, and ask them if you can explain the rating system to them. Don't be judgmental though, if they truly don't care, it isn't your job to parent their kids.
That's what these politicians need to learn. Especially in democratic countries, it's not your job to parent people's kids.
