The question I'd have for such parents is just: Ok, no violence, no sex/nudity/whatever else you wouldn't want your kids to see, no reality whatsoever. Just a company firing episode after episode of their cutesy cartoon characters at your kids, interrupted by commercials telling them that they can have those cutesy cartoon characters at home and that they have to buy every piece of plastic crap Disney poops out?
There's a time and a place for everything. I expect my son to know about sex, nudity, violence, and war...aka "reality" someday, but that doesn't mean he has to be educated about those topics at an age where such knowledge might negatively impact his psychological development.
