The postmoderns end up alienating a vast majority of normal modern people, making them feel confused, insulted and frustrated. And once that has gone on for a long while, the majority revolts and begins voting with Trump and the nationalists. Non-postmodern people begin to feel a subtle sense of revenge when somebody speaks out against political correctness.
So are those who blame postmodernism (at least partly) for Trump, taking a metamodern view of life, though they may or may not know it?
