This morning, The Today Show featured an interview with Dan Merchant of the book and documentary Lord, Save Us From Your Followers which appears to be about the conservative/liberal religious cultural divide in America. Apparently, Merchant wears a bumpersticker outfit and interviews people on the street about their religious views. The documentary also featured a culture war game show pitting liberals versus conservatives, in which the liberal team "stomped" the conservative team in their knowledge.
It sounds like an interesting and entertaining documentary. My only apprehension is that Dan Merchant and the Oregon production company seem to come from the conservative Christian perspective. Of course, my apprehension seem to confirm the documentary's premise of the American religious divide.
