It's certainly not my invention. The concept comes from the Frankfurt School Marxist, Herbert Marcuse's essay of the same name. Marcuse is basically the poster child of the current "woke" Marxist nonsense that's going on. It is a good and succinct way of describing their behaviour though. Something even normies can somewhat grasp. Which is important as many will just deny the Marxist origins of what is happening. Once you point out that what they are doing is literally straight out of a Marxist "how to" manual, that denial produces significantly more cognitive dissonance. If you can break through and show how these radical leftists are implementing Marxist ideologies, it's easier to get people to look further... into the education system (SEL - Social and Emotional Learning) and the DEI stuff which is all Marxist.
