Dinesh D'Souza recently presented the philosophical case for God on the Riz Khan show. Richard Dawkin's appeared on the show as well, but told producers that he would not debate D'Souza face to face.
It appears as though the world's so-called "leading athiest" is afraid to spar in public. Of course, if it looks like a chicken and acts like a chicken...chances are...Dawkin's is a chicken. Balk, balk, balk. The clip was broadcast to more than 20 million viewers worldwide. You can watch the clips or read more about the situation on Townhall.com:
