Yeah, which was a response to Muslim armies continually attacking Christian enclaves.People pick and choose which Commandment they will obey. Moses (if even real), wrote "thou shall not kill," then proceeded to wipe out entire villages on his command. When his followers found a stranger in the wilderness who was gathering wood on the Sabbath, they took him to Moses to see what he would advise. He deliberated and instructed his followers to stone the man to death (so much for thou shall not kill), which they did.
Bbbut the Crusades!!!!
