Who are the literary heroes of the postmodernists? Martin Heidegger, Friedrich Wilhelm Nietzsche, Paul de Man. None of those men was a friend to liberal democracy. All of them were anti-Enlightenment, anti-rationality, anti-science.
Heidegger, perhaps the greatest philosopher of the 20th century, was a member of the Nazi Party. De Man wrote pro-Nazi articles in his native Belgium. Nietzsche made war upon Christianity and proclaimed the death of God.
At least those men could write. The tenured radicals who inhabit our universities not only lack that ability, they lack the ability to make sense of what they've read. They give mediocrity a bad name.
