They try to pass off the falsehood, particularly related to the Reformation, that religion is the biggest cause of war in the history of the world. That is patent nonsense. The wars of Christianity, according to the research done at the history department of Baylor University, account for about 5 million people being killed, whereas the wars of atheism in the 20th century alone, or secularism in the case of World War I — 20 million people died in World War I’s nationalistic war, which is a secular ideology — that was three times as many as the Christians. Hitler’s and the Japanese Empire’s war was 50 million, and the KGB said that 62 million were starved to death or executed during the Soviet period. And with China, they don’t know yet; guesstimates go as high as 200 million.
