Allah set them off 1500 years ago.
Mohammed said, “Follow me and I will lead you to victory, pillage and rapine, all in the name of serving a god who will welcome you into a sensual paradise if you are ever killed by one of your victims intent on keeping his life & his stuff.”
“Qualifications?”
“Rape, murder, arson, & rape.”
“You said `rape’ twice.”
“I like rape!”
Fourteen centuries worth.
