This trend of parents groups passing the buck onto movies/music/peers/videogames/internet et cetera is going way too far.
Instead of taking an active interest in what their child reads, watches, plays, and who they interact with, they expect the rest of society to take care of THEIR children.
This whole business in the news about children accessing the 'hot coffee' scenes in GTA: San Andreas is utterly ridiculous. Why would a child have a mature rated game in the first place? I think little Johnny probably doesn't have the resources to spring for the XBOX and a game himself, the money's coming from somewhere.
