I think it's pretty well established that Ergun Caner faked a Muslim background in order to ride fear and bigotry into evangelical stardom by Muslim bashing. He's not the only one. There's a lot of demand for such nonsense in neoconservative circles.
OK, things happen. Scammers sneak through. What can you do? How about not booking a guy like Ergun Caner at Christian conferences as if he's an expert on Islam? But no, at "Veritas Evangelical Seminary" (whatever that is) we have Ergun Caner lecturing on "The Secrets of Islam." I'd think he'd be embarrassed to show his face and even talk about Islam at this point. Not in the evangelical world apparently.
