Blacks in America are similarly delusional. It was Christianity within Europe that opposed slavery and eventually forced an end to it. The papacy forced the Spaniards to end slavery in Latin America, and British Evangelicals forced an end to it in Europe and America. Long before and long after the Europeans got involved in the slave trade, Arabs were slavers. In fact, the whole history of the Muslim world happens to include slavery as a central institution. For example the Mamelukes, a corps of elite warriors, were Christian slaves kidnapped as children from Europe.
American blacks who blame Christianity for the treatment of their ancestors are ignorant of history--which is not surprising, considering what distorted versions of history are taught in our schools and colleges. Many of their ancestors were taken by Arab slavers before they were sold to the Europeans. And their brother Africans in Sudan are being enslaved by Muslim Arabs to this very day.
This is the saddest irony of the mass exodus of Black Americans to Islam. While there were certainly oppressive aspects to the way Christianity was inculcated to slaves, I can't imagine changing a name that was EARNED through the sweat and toil of my ancestors to one of a culture that STILL practices slavery in Mauretania and Sudan(and everywhere else, let's be honest)
