"It is strange to witness the passion with which some secular figures rail against the misdeeds of the Crusaders and Inquisitors more than 500 years ago. The number sentenced to death by the Spanish Inquisition appears to be about 10,000. Some historians contend that an additional 100,000 died in jail due to malnutrition or illness.
These figures are tragic, and of course population levels were much lower at the time. But even so, they are minuscule compared with the death tolls produced by the atheist despotisms of the 20th century. In the name of creating their version of a religion-free utopia, Adolf Hitler, Joseph Stalin, and Mao Zedong produced the kind of mass slaughter that no Inquisitor could possibly match. Collectively these atheist tyrants murdered more than 100 million people."
Atheism, not religion, is the real force behind the mass murders of history
