Example of Dialectical Attitude to Religion

I came across this delightful example of the dialectical spirit in action vis-à-vis religion. Magician Penn Jillette, an Atheist, describes in the clip (from his blog) an encounter he had with a Christian at a 'Penn & Teller' show.

The dialectical result presented in the clip is not agreement, or conversion, but respect & understanding--and these are glory enough compared to the malevolence and antogonism common in polemics.
