Having to defend your position in the face of direct and personal opposition is healthy for democracies and other living things. The worst ideas, the worst ideologies, always insist that they have a sole lock on the truth of things and always act in such a way as to undermine or suppress debate. And that is as un-American as a thing could be. The greatest of the ideas underlying America, what makes us truly special among nations and among experiments in governance, is that America is a place where the free marketplace of ideas is not only enshrined in the national consciousness, it's actually built in to the system.
