A new idea of tolerance has taken hold of Western culture. We now believe that if we say someone is mistaken, we are being intolerant. If we say everyone’s view is correct and no one is mistaken, we are tolerant.
How can I be tolerant of a person if I think he’s correct? That sounds backwards. I can only tolerate him if there is something to tolerate—his mistaken view. On the other hand, how is it intolerant if I say someone is mistaken? If you physically attack a person or throw him in jail because he holds a certain view, that’s intolerant.
