I might check it out as well.
Steve Taylor, who back in the 1980s and early 1990s, was a fundamentalist who had reason and he made fun of fundamentalists who didn't have reason. But, it seems that in the 2000s, he's gone through some transformation and I don't really know what direction he's taking.
