To be fair, there were many years of social injustice prior to, during, and after the Civil War. Thing is, it ended 137 years ago, and the civil rights movements of the '50's and '60's went a long way to bring awareness to the intolerance of whites. Affirmative Action was intended to bring a bit more parity to race in the workplace- with debatable results. In the end, there can be no real justification for such a silly demand.
More, even if there was a basis, it wouldn't happen. Nation of Islam isn't exactly friendly to the U.S.A., and creating a virtual country within our country with militant Muslims in control is a little less than... likely. Heck, knowing Louis, he'd be demanding weapons for "self defense".
