Anyone care to guess how many people were killed worldwide fighting wars spurred by religion in the last 2,000 years?
If nothing else, religion has been a roaring success at keeping the population in check.
A good example is the Ancient Israelites. Their book says they were instructed by God to kill every man, woman, child, infant, and even the livestock of particular regions or ethnic groups with the aim of completely destroying that group of people. They even committed mass genocide against other Jews. The Ancient Israelites made the Einsatzgruppen look like kindergartners.
