Such as????? If you let your kids watch ABC, CBS, or NBC between 6am to 10pm, you're supposed to have some expectation that this kind of thing isn't what's shown. Where was the "R" rating ahead of time? I can see you condemning those who might buy cable and MTV then complaining about what MTV showed their kids.
My kids are younger, but I can tell you I monitor the toons they watch as well. Believe it or not, a saving grace has been boomerang. Cartoon Network just sucks IMO. And (even though I am a metal head), my kids like the cuntry channels. Been trying to keep up with those as well...
