(The debate starts about 14 minutes into the show, so you'll probably want to fast-forward with the slider to that point.)
Harry Browne is one of the most clear-headed, rational thinkers I have ever encountered. In this debate, he not only shoots down every one of Dozier's arguments, but does so with complete civility, grace, and friendliness. He may not have converted this preacher within the short time span of the debate, but after Browne countered every point Dozier made, Dozier simply had nothing left to say, other than Browne was going to hell. More importantly, Browne really made him think.
