So, i got this theory. Listen. 
Jews invented their religion for their own use. Then they invented christianity (and thus islam too) for goys over whom they ruled (turn the other cheek and be submissive to your master). All the while jews got their talmud, Torahs and all the "chosen people" stuff over the goys. Thus Christianity is the biggest scam a man had ever invented. Now islam is a bit funny, because its a runaway project that eventually turned on jewish creators, a backfire if you will. Now you know.
