If someone watches football as obsessively as folks play WoW then I'd agree. But if your child falls over and needs attention you can get up and deal with it without "letting down your group/team/guild". I know of multiple cases of child neglect by players... indeed, my wife and I gave up WoW cold turkey when we realized one of our twins had a fever and we hadn't noticed for several hours because we were so engrossed in the game. Haven't played seriously since.
