Everyone gets their shorts in a bunch when the government tries to step in and "watch out" for the kids. But what they should be doing is looking for the parents that don't keep an eye on their kids. The reason the government gets involved because parents are too lazy to say no and make their children mind them. If the parents said no, and the kids got a hold of the inappropriate games with out the parents permission the kid should get in trouble. But that is too hard for our lazy parents in this country.
I am a single father and i keep an eye on my sons internet activity and what games he plays and has access to at home. He knows to ask if he can play a game because if he doesn't and plays a game that i don't approve of the whole system is put away and he is grounded.
You want to keep inappropriate material from your kids then BE PARENTS, get off your butt and punish your kids when they break the rules, let them know who makes the rules and that there are consequences if the break them.
