Because it is a fact that very few anorexic women are black. Facts can't be racist. The "you don't say" is because anyone who is honest can see how many fat black women there are in America. If you claim you never noticed this you're probably one of those fake "color blind" assholes who pretends not to see what everyone else does because you think you're suuuuch an enlightened person.

You acting like black people can't handle a true statement about the weight problems in their community is more racist than whatever you think was going on. Black people don't need you to defend them.
