The Critical Theory of Marxism was fine-tuned by the “Institute for Social Research,” which is better known as the Frankfurt School. Critical Race Theory is a recent revision, but it is all a Marxist approach to teach hatred of one’s own society to make it easier to convince them destroy it and replace it with communism.
If there’s any person who deserves hate and scorn, it’s Karl Marx and his unholy philosophies. It’s those policies that destroy the notions of freedom and equality, not to mention the 150 million people killed by some of the most tyrannical governments on earth.
