"Political Correctness" and "Cultural Marxism" are one and the same.

Cultural Marxism method
Two Marxists theorists, Antonio Gramsci in Italy and Gerog Lukacs in Hungary independently came up with an answer to why the working class, after WWI, did not embrace Marxism: the influence of traditional cultural Christian Religion. Lukacs was a major influence in the Frankfurt University, Institute for Social Research aka the Frankfort School. This school translated Marxist economic values into cultural values. The Frankfurt School’s key to success was crossing Marx with Freud. They argued that under Western culture people lived under psychological repression. From psychology they also drew the technique of psychological conditioning. The method is to vilify every one who defends traditional culture by labeling them as a "Racists," "Facists" and/or "Tyrant." All such opponents must submit to "sensitivity training" aka, brainwashing in the "new normal."
