At last count more than hundred people have posted comments about my interview this weekend with Scott Simon on NPR.  Many of those responses have supported the assertions I make in "Denialism," others have criticized me with great vigor and still others, it seems, would serve as examples of  the problems of denialism the book attempts to describe. Issues like vaccination, the proper role of organic food in feeding the world, and the use of vitamins and supplements certainly do seem to get under people's skin.
