So...OK...so you bring up Robert Byrd, ignorant of his renunciation of his past, and then completely abandon him the moment you realize how you've been talking out of your ass.
Robert Byrd renounced his racist past and supported Obama. So when are you going to renounce your racism? Robert Byrd is a better man than you ever will be, even though he was a Klan member.
