In response to the blog http://garyng44.wordpress.com/2006/04/09/cartoon-nudity/ I definitely agree with you that family guy is a great show, I own every DVD released, I do agree that it is possibly obscene too. My opinion about children's exposure to the cartoon nudity differs a bit though. More specifically, I think there is a bit more involved then just looking at if kids watch it.
Technology today allows for parents to block our certain TV channels, and some even allow for specific shows. Family Guy is a adult cartoon with adult themes most of which are OK for kids over the age of 14, and possibly a bit younger with the way kids mature today. The adult themes and cartoon nudity, that leaves out genitals and leaves that area without anything, are mild and most children wouldn't get the more adult jokes. (I don't get some at first!!!) This question of what children watch and it being acceptable or not is not new at all. The Simpson's faced the same contervisey when it was first aired too. What I believe the real problem is here in both cases is peoples parenting skills today! I seems as-though parents don't pay any attention to there children, or at least very little, nor do they encourage them to do other things than watch TV. When I was young I never wanted to watch TV unless it was a movie, I wanted to be outside or at least do something other than watch TV, it was boring. I do believe my parents are exceptional parents as I look back on my life and that helps a lot, but they didn't do too much extra.
All it takes is good parenting or at least a bit of attention to monitor what you kids watch. Kids will be kids and yes, they may watch shows outside of your home that you don't allow, but, again good parenting could pervent this. My point being if you believe as a parent that Family Guy, and other adult cartoons, are obscene handle it the right way by being a good parent and raising your children with morals so they will not be interested in them. Furthermore, parents good or bad should monitor what their children watch all the time and if there are truely concerned about what they watch don't give them the access to it!
