My reading is that Dick Gregory did not hate white people. When two NFL teams were playing, in his heart he’d root for the one with the black quarterback. I admit, I root for white defensive backs ;)
He saw his race as troubled, and put upon. He may have harbored unhealthy conspiracy theories, but he struck me as a good-natured scold. He pushed the same old 1960’s bromides that were not even useful in the 1960’s. He was never an Al Sharpton or Barack Obama.
Why then would he have accepted an invitation from the notorious black racist Louis Farrakhan to speak at his "Millions More Movement" rally?
