Sorry, I guess the lawsuit started sometime in February, but I only heard about it yesterday. Craigslist is being sued for housing discrimination, because of roommate wanted ads that specify "female" or "Christian". http://www.law.com/jsp/article.jsp?id=1151399126165 The issue for most people is whether Craigslist is liable for what the users are posting, but for me it is something else. For a landlord, it should not matter who rents your place as long as he gets paid, so make it a crime for discrimination based on ethnicty, gender or religion for the landlords. However, "roommates" are different. It is perfectly understandable for a woman to prefer a female roommate. Forcing an openly gay person to live with a pious Christian who believes it to be a mortal sin would not serve anybody's interests. I know quite a few foreign students who end up boarding with people from the same country and I don't think that is morally repugnant. The federal law should distinguish between a landlord and somebody looking for somebody to share their living quarters if it does not already.
