D.A. Carson (a very smart guy who writes really well) has recently put out a book that I haven't read but have wanted to (just can't bring myself to buy it), called The Intolerance of Tolerance In the book, Carson approaches the tolerance conversation by noting that there is "old" tolerance and "new" tolerance. The old kind is the kind that is actually somewhat beneficial. Carson says that old kind accepts the existence of different views. By contrast, the new kind of tolerance accepts different views. Pretty significant difference there.
