The Frankfurt School is an important subject. The Stogy German Professor [Marcuse] finds himself in Southern California and finds that the land of eternal sunshine and surfing and girls is all really Nazism [just hidden and waiting to break out onto the surface.] [The One Dimensional Man of Marcuse became the main text of the student radicals.]The idea off the alienation by technology of Heidegger gets accepted by the "Greening of America" of the 1960's. The whole mixture of Freud and Marx as the liberators of Mankind becomes the norm.
The attempt to understand surfing and girls as proto Nazism had it effect as we see today with the consistent onslaught against all America values by the Left.
[The reason why these German professors were doing this is the same as "Antifa" working on getting away from Nazism. So their solution was to go to the Far Left and Show that America was too dangerously in the center. [In the 1920's there was no center.]
[But I claim that the center is not the place of danger but rather the right place to be. But to the Left there is no center. if you are not a Freudian Marxist then you are a Nazi.]
