Trump has his eye on the contemporary Left’s extremism, but this is not so much the statist Left that the libertarians oppose, nor the values-and-autonomy Left resisted by the religious Right, but the anti-American Left. This Left plunged its knife into our politics in the 1960s and has been twisting it ever since.I think part of Trump’s apparent lack of a strategic plan is due to the fact that he does not realize that there is such a thing as the anti-American left. He understands that bad decisions have been made on immigration and trade but that this was due to negligence, not pure malevolence and destructive, revolutionary purpose. It is hard for decent people to understand that they are up against pure evil. But that is what we face. What the left has in store for the world is nothing less than the destruction of Western civilization.
The Old Left had opposed American capitalism, the Progressives had condemned American plutocracy, but not until the ’50s and ’60s did a significant faction of the Left begin to blame the American masses, not the elite, for the country’s sins. The people became the problem. They were racist, materialist, imperialist, sexist, and sexually inhibited, according to the original catalogue of sins; later the phobias were discovered—homophobia, Islamophobia, transphobia, and so forth. Together these comprise pretty much the irredeemable sins Hillary had in mind when she condemned Trump’s voters as deplorable.
