Milton Friedman on Intolerance, Liberty, Mises, Etc.

In a blog post here a few years ago (Friedman and Socialism), I mentioned a 1991 Liberty article by Friedman that I remembered where he said he was in favor of liberty and tolerance of differing views and behavior because we cannot know that the behavior we want to outlaw is really bad. In other words, the reason we should not censor dissenting ideas is not the standard libertarian idea that holding or speaking is not aggression, but because the we can’t be sure the ideas are wrong.
