“As many know, there once was a great boxer named Cassius Clay. He converted to Islam in 1964, seemingly bothered that Jesus was portrayed as “a white with blond hair and blue eyes,” as he put it, and took the name “Muhammad Ali.” Of course, the irony of this is that despite being intensely aware of his slave roots, Ali rejected the name of an abolitionist (Clay) and took the name of a slave-owner (Muhammad). It also perhaps eluded him that Christians were the first ones to outlaw slavery, while Muslims give black Africans rope and chains to this day.”
