Unfortunately it would seem to me that many Christians are prone to anti-Muslim bigotry. Ergun Caner recognized this after 9/11, so he pretended to be a formerly dedicated Muslim ex-jihadist. He could invent stories that gullible Christians would enjoy about how Muslims are bloodthirsty crazies that want nothing more than to see Christians slaughtered.
The fakery made him a star. Before he knew it he was President of a major Christian seminary. He was the guy called in to train marines in the jihadi ways of all those Muslims that needed to be killed over in those oil rich regions.
The guy would pretend he could speak Arabic and would literally invent Arabic sounding phrases to deceive his gullible audiences. He'd describe Islamic beliefs and get basic things wrong. Some really hilarious stuff. An absolutely pathetic display.
Having been busted he's not saying much about it. But he has apparently hired an Indian based PR firm to spam the web and divert people from discovering these embarrassing details.
One would think Christians would abandon him in droves. Some have. But many stand by him and make excuses for his transparent lies. Such as Norman Geisler, John Ankerberg, Ron Rhodes, and others. Punishment at Liberty has been mild. He's been demoted from President to Professor.
Geisler's defense reads much like his apologetics. Seriously. What's sad is that I once regarded him as an intellectual titan.
