That's a fascinating list. The violence associated with religion for 10 centuries.

So, let's compare the opposite. In the past century there have been about 100,000,000 people who were killed in the pursuit of communism.
USSR, 20 million deaths; China, 65 million deaths; Vietnam, 1 million deaths; North Korea, 2 million deaths; Cambodia, 2 million deaths; Eastern Europe, 1 million deaths; Latin America, 150,000 deaths; Africa, 1.7 million deaths; Afghanistan, 1.5 million deaths; the international communist movement and communist parties not in power, about 10,000 deaths.
Communism compiled a lengthy enemies list, which included political parties, clergy, intellectuals, shopkeepers, many ethnic groups, and other “socially dangerous elements.” Enemies were starved and worked to death; executed with bullets, shovels, and hammers; devoured by dogs; lit on fire; and made to kill one another for their capturers’ amusement.
More than bodies endured torture. Language was tortured: concentration camps became “re-education” camps. Minds were tortured: executions often followed “confessions” of guilt. The list of crimes punishable by death or imprisonment included criticizing the regime, owning a gun or radio transmitter, stealing a few ears of corn from the collective, and “taking part in commerce.”
