Actually according to Indian historian K.S. Lal, Islam killed around 80 million people during the centuries long conquest of the Indian subcontinent alone. That's not even counting what they did to the Middle East or the amount of bloodshed, imperialism, and r@pe they spread across Eastern Europe during the Ottoman Empire. Interesting you mentioned Africa when the Arabic/Islamic Slave Trade did more harm to Africa than the Transatlantic. Historian Dr. John A. Azumah estimates the death toll to have in the upper millions. And it may surprise you further to know that the only reason there was a Transatlantic Slave Trade was because most of the Orthodox Christian lands--traditional sources of slavery (fun fact, "slave" comes from Slav)--were already enslaved by the Ottomans. But even beyond their historical atrocities, whereas Christianity with the exception of some Protestant fundamentalists do not sanction such violence and treachery, Islam actually does. It isn't just the radicals like the media would have you believe. The peaceful ones are actually the exception. My personal friend Dr. Isa Almisry is PROFESSOR of early Islamic studies and even he says that Islam is an inherently violent and backward religion. He's Arabic btw, and Orthodox.
