What do Christian fundamentalists have against set theory?

Perhaps because I skim-read it, but I couldn't seem to find the part where he (i) actually found that Christian fundamentalists in general have something against set theory, and (ii) determined that it was their Christian fundamentalism and not some other factor that made them opposed to it. Instead, there was just a vague ramble about a particular publisher that doesn't like modernism. Reading this post felt a little reminiscent of the famous newspaper story: "SIXTY HORSES WEDGED IN CHIMNEY. The story to fit this sensational headline has not turned up yet."

Perhaps fundamentalists are proving the validity of evolutionary theory. Maybe they are a side branch of homo sapiens in which intelligence is curiously underdeveloped, that brain capacity being occupied by blind dogma and superstition. Due to interbreeding perhaps?

One element in a large set, evaluated out of context, is not necessarily representative of all elements in the set.
