SSC famously made and extended this argument a few years ago [0]. I like that essay's example of creationists even better, because it's a shockingly huge group of people - over 40% of Americans literally believe that the Earth was created in its present form in the last 10,000 years or so - and for all intents and purposes its overlap with the readership of PG, HN, SSC, or whatever is 0.
