Dinesh DSouza writes a nice piece taking apart the oft repeated myth that religion is the culprit in all the most destructive wars of history.
This reminds me of a time sitting in one of the required (but not so interesting or rigorous) courses I took in graduate school. The professor, who was a nice man but not the most engaging teacher, made the point in passing that more people had died in the name of religion than anything else in the history of the world. It sort of woke up the room for one brief shining moment. The lefties in the class became engaged as they finally heard a claim being staked--something that was not milquetoast from their point of view. I looked around the room at some of my like-minded friends and we prepared to go to battle. But we overlooked one of our more quiet friends who usually sat in the back of the room and rarely made comments in class. To our amazement, he slowly raised his hand. When called upon he asked the following question, "What religion, exactly, were Hitler, Stalin, Mao, and Pol Pot working to advance?" And then he put his hand down, put his head down, and went back to reading whatever it was that he brought with him to pass the time. There was stunned silence in the room. Class was hurriedly dismissed.
