Consider what sort of a reception a person might get if they were to proclaim that all that Holocaust stuff should be left in the past. Anti-Semitism? Pshaw! That's just a bunch of race baiting!! I think said person would be instantly taken down by just about everyone across the political spectrum.
So, why isn't this the case with the issue of race and African Americans in the United States? Any sort of claim of racism is heavily scrutinized and often vilified, especially by the right. Why?
