And no one is saying you can't acknowledge that. But it has been done to death. It is not a defense for the rapist. People for whom their first reaction to hearing a rape accusation is, "well, she shouldn't have been drinking that much/in that situation/wearing that" are a part of the problem. When they feel like they have to say that every time there is a discussion about rape, when everyone already knows, they are a bigger part of the problem. Of course you shouldn't go to a black neighborhood and pick a fight, but when you do and the police come afterwards, they are going to believe you and investigate the crime. Many times women don't even get that.
