Well, apparently "one" of the things he said that some white folks with special white-folk-pretzel-logic (was that racist?) thought was racist was that the rich, white guys running the country intentionally injected HIV into the black community. Now, okay. That's a conspiracy theory I've surely heard for years and which I wouldn't say has a lot of merit, but there was that pesky Tuskegee experiment, the 40 year long study in which black men were allowed to suffer and die AND infect their wives and children with syphilis even though penicillin became readily available during the study. The American (hell, white Western) medical establishment has hardly done much for its PR in the black community.
Also, I wonder... Was Dr. Martin Luther King, Jr., trotted out by Democrats and Republicans alike on the regular, also a traitor?
