I think it's generally a bad idea. I don't think people can post their thoughts on it without being inflammatory. There definitely shouldn't be a whole board. I think that if there has to be something it should be one thread in the off topic section (perhaps in Drinking the Haterade). There are way too many trolls to have more than one thread devoted to Affirmative Action.
I don't look for fights on LSD but if someone says something inflammatory I just can't let it slide. What's wrong with me?
