I've started a community called colorful_rage. It's a place to vent and rant about issues of race. Any other forms of discrimination are open for discussion too, but it's mostly for race issues b/c I didn't see a community like that already out there (like feminist_rage and queer_rage. Feel free to join, and if you're respectful and not a person who just likes to stir up shit, I'll approve you.
