That claim is simply false.
The deadliest events in human history were not primarily religious wars. The two World Wars alone killed tens of millions of people. Add in the atrocities committed by explicitly atheistic regimes such as Stalin's Soviet Union, Mao's China, and Pol Pot's Cambodia, and the death toll reaches well over 100 million.
Historians generally estimate that religious wars account for only a small fraction of humanity's violent deaths. People have killed for power, territory, ethnicity, resources, politics, and ideology far more often than for religion.
According to the work of historians Charles Phillips and Alan Axelrod in the multi-volume Encyclopedia of Wars, only about 123 of 1,763 recorded wars were classified as primarily religious in nature.
That works out to roughly:
123 ÷ 1,763 = 6.98%
So approximately 7% of wars were primarily religious wars.
If we're going to discuss history, let's discuss actual history.
Please Scott.
Try to get some help ..
REAL help.. not any of that religious stuff !
In history people have died/been slaughtered for, land, property, food, mates, territory, etc
But studies have shown, more have died/been killed for/in the name of god than for any other reason.
