Part 2 of Richard Dawkins' The Enemies of Reason can be found here on Google Video. I am watching it now; it looks good so far. Part 2 is mostly about quackery and weird health claims.
UPDATE: I think it's pretty good. My only wish is that Dawkins would turn his skeptical eye toward big government. For the life of me, I just don't understand big-government-atheists. The same mindset that led me to reject the idea of faith in god led me to an understanding of the limits of government.
