See that's what we're saying. Religion just causes war. Just look at the time of the crusaders. It was a time of mass murder just because of religion.

Also I'd just like to point out the crusades happened because European world powers wanted control over the middle east, so they had Christianity think up a holy war to get everyone to invade.

A good comparison is how we blamed Iraq for 911, and then proceeded to invade Iraq for years under the false pretense that Iraq struck first. In reality, 911 was most likely an inside job, and everyone knows that we only invaded iraq for its oil; same as how the Christian leaders invaded the middle east for its land and for glory, not for god.
