A man I have known since grade school changed his name, years ago, to an Arabic one. He told me he rejected Christianity as "the white man's religion that justified slavery." He argued Africans taken out of that continent were owed reparations. "From whom?" I asked.
Arab slavers took more Africans out of Africa and transported them to the Middle East and to South America than European slavers took out of Africa and brought to North America. Arab slavers began taking slaves out of Africa beginning in the ninth century -- centuries before the European slave trade -- and continued well after.
In "Prisons & Slavery," John Dewar Gleissner writes: "The Arabs' treatment of black Africans can aptly be termed an African Holocaust. Arabs killed more Africans in transit, especially when crossing the Sahara Desert, than Europeans and Americans, and over more centuries, both before and after the years of the Atlantic slave trade. Arab Muslims began extracting millions of black African slaves centuries before Christian nations did. Arab slave traders removed slaves from Africa for about 13 centuries, compared to three centuries of the Atlantic slave trade. African slaves transported by Arabs across the Sahara Desert died more often than slaves making the Middle Passage to the New World by ship. Slaves invariably died within five years if they worked in the Ottoman Empire's Sahara salt mines."END OF QUOTE
