You might find out what you are talking about before you side with the video makers. No one said the cartoons were evil. The Cartoon characters, however, are being used to promote homosexual and feminist ideology to elementary kids. Are you okay with that?
I think it's a waste of time. Cross-dressing and gender-bending have been such a staple of kids cartoon for so long, that I don't think elementary kids will get any political message.
I don't think schools are a place for any political message. But, since I'm socially libertarian and gay-tolerant (to say the least), I worry more about anti-Capitalist, pro-environmentalist politics in the public schools.
Mind you, my son goes to a non-religious private school and my daughter did until high school.
