Islam has slaughtered more than 669 million non-Muslims since the year 622.
According to estimated figures, more than 80 million Christians were killed by Muslims over a period of 500 years in the Levant, Egypt, Mesopotamia, Greece, the Balkans, Spain, Italy, the rest of Europe, and the Caucasus.
In India, the Hindu population was also reduced from 600 million to 200 million at one point. In the same period, entire Buddhist populations were wiped out in Afghanistan, Malaysia, and Indonesia.
Indeed, no ideology has been as genocidal as Islam.
