muslims in various parts of the word (e.g., Sudan, Mauritania) still enslave "infidels", and sell slaves to rich muslims in the Gulf States and elsewhere. Most of these slaves are black. muslims also hold many other "infidels" in dhimmi status, and are threatening to re-introduce dhimmitude in other muslim countries.
islam has been the biggest slave system in world history, and still is today!!!! Meanwhile the taqiyya-practicing muslim would-be dictator Barack Hussein Muhammad obama bashes the great Commonwealth of Virginia for celebrating Confederate History Month, all because of slavery. Partners in Hussein's hypocrisy are the legions of phony academics who bash America (especially the South) and exalt islam, all while hiding islam's truly barbaric past and present.
As for Alex Haley's "Roots", it was plagiarized from an earlier novel, and was NOT about Haley's family history. The phony, plagiarized "Roots" (the book and the TV series) has done untold damage to America and her culture, leading us to emphasize "identity politics" over Americanism.
There is a good book on this-—an academic, scholarly book-—called “Christian Slaves, Muslim Masters.”
