If you are going to ban discussion of Racism here, you may as well change the name Mothering Dot Commune, The Natural Family Living Community for White People Only. And I'm not being sarcastic with that.
Please, Please, Please do not even further the idea of banning Racism from discussion at a mothering community.
We cross posted, but that is exactly what I was trying to say - you just did it better. I'm NOT a MOC, but if my 5 yo ever comes home from school saying the N word, I want a community of NFL/AP moms (some of whom have been on the receiving end of that word and others) with whom to discuss how to deal with it.
I'd also like to say that, with as much animosity as we see on those threads, people are learning. It might not seem like it when people are sniping at each other, and the same people are taking the same side in every argument - but people are learning. How many times have you seen some one say "I never knew the word jipped/gypped was racist! Wow, I won't say it anymore!" For every one person who chimes in and says something like that, think of how many more read the thread and thought it to themselves?
