(T)olerance in many Western societies increasingly focuses on ideas, not on people. … It is especially difficult to be tolerant of those people whose views are so far outside the accepted “plausibility structures”.
… The gospel of relativistic tolerance is perhaps the most “evangelistic” movement in Western culture at the moment, demanding assent and brooking no rivals.
… significant changes in what “open-minded” means. It no longer means that you may or may not have strong views yet remain committed to listening honestly to countervailing arguments. Rather, it means you are dogmatically committed to the view that all convictions that any view whatsoever is wrong are improper and narrowminded.
