According to some calculations, the Indian (subcontinent) population decreased by 80 million between 1000 (conquest of Afghanistan) and 1525 (end of Delhi Sultanate). — Koenrad Elst as quoted on Daniel Pipes site
80 Million?! The conquistadors’ crimes pale into insignificance at that number. No wonder Hitler admired Islam as a fighting religion. He stood in awe of Islam, whose butchery even he did not surpass.
Over 110 Million Blacks were killed by Islam.
… a minimum of 28 Million Africans were enslaved in the Muslim Middle East. Since, at least, 80 percent of those captured by Muslim slave traders were calculated to have died before reaching the slave market, it is believed that the death toll from 1400 years of Arab and Muslim slave raids into Africa could have been as high as 112 Millions.
