Is Trump a fascist? When are we justified in using the "f" word to describe a right-wing politician or movement that we legitimately find frightening?

That’s the deeper – and disturbing -- question in the presidential debate.

In ostensibly promoting tolerance, the essential core of liberalism, left wing extremists have taken on an ill-advised and misguided campaign to enforce an extreme version of political correctness, a form of intolerance that is ironically self-destructively anti-liberal. There is no constitutional right not to be offended.
