You are so right Chaim, they are very dangerous to whoever is in their path. Genesis 16:11 The angel of the Lord says to Hagar, You are now with child and you will have a son. You shall name him Ishmael, for the lord has heard of your misery. "He will be a Wild donkey of a man; his hand will be against everyone and everyone's hand against him, and he will live in hostility toward all his brothers." Even against his Muslim brothers!
