Educate both, perhaps? Someday those kids will be adults and have kids of their own, with hopefully more inclusive and accepting views. Perhaps it will even encourage them to challenge the ideas, words, and views their parents present.

Or is it because the school allows us to force kids to listen to things that adults would walk away from? These classes are never aimed at university students or other young people, just the captive audience of a gradeschool classroom. I question the effectiveness of any scheme that can only fly in such controlled environments.
