Ravi Zacharias is a Liar? Oh my!

Many of us claim Christian apologists lie to defend their faith. I have a whole chapter documenting this phenomena in my book, "How to Defend the Christian Faith: Advice from an Atheist" (see link in the sidebar). So with regard to Zacharias, since he has knowingly lied about his credentials, why should anyone accept his apologetical defenses of the Christian faith? LINK. I don't see why anyone should.
