Johnson is a radical skeptic, insisting, in the best Socratic tradition, that everything be put on the table for examination. By contrast, most skeptics opposed to him are selective skeptics, applying their skepticism to the things they dislike (notably religion) and refusing to apply their skepticism to the things they do like (notably Darwinism). On two occasions I’ve urged Michael Shermer, publisher of Skeptic Magazine, to put me on its editorial board as the resident skeptic of Darwinism. Though Shermer and I know each other and are quite friendly, he never got back to me about joining his editorial board.
