There's something that has always struck me as ironic about the Nation of Islam. While the Arabs probably didn't start the slave trade in Africa in the first place, they certainly helped to maintain its existence. But they were sold to white masters (ostensively Christian) who used them in the plantations. I just think it's one of the great ironies of history that a lot of Afro-Americans have become Moslem, given that their ancestors were probably captured initially by Arab slave raids, or traded from place to place by Arab middlemen.
