Some excerpts from the Bible are nonsense and were written by different authors, and many of these teachings were tempered by the arrival of Jesus Christ, who went off in quite a new direction. Most Christians understand where the craziness occurs in the OT, unlike locos like Phelps, and ignore it. But because the Koran is inspired solely by Mohammed Muslims are stuck with whatever the man said.
ISIL or ISIS, whatever name it is going by, is no more Islamic than Adolph Hitler was Christian. Yes, Hitler claimed to speak for Christians. So did Jim Jones. So did Timothy McVeigh. So did the Ku Klux Klan. And so did the Norwegian guy who killed all those school children. So do we brand Christianity as a false and hateful religion? Of course we don't. The fact that Muslims all over the globe, including even the extremist Wahabis, are condemning ISIL speaks for itself.
