Hate crimes legislation has its roots in the communist-inspired, so-called Frankfurt School founded in Frankfurt, Germany by Bolsheviks in the 1920s. Its goal was to implement communism in the West quietly by gradually subverting popular culture -- a movement known as Cultural Marxism. One of its leading lights, Herbert Marcuse, opined that the prevailing Western social order is repressive by definition and discriminates against minorities simply by existing.

This creates a phenomenon he called "repressive tolerance"

Instead, he proposed what he called "partisan tolerance
," i.e. tolerating the views of those "repressed minorities" only -- who Marcuse assumes share his partisan hatred for everything noncommunist -- while actively muzzling the views of the majority.

They have been practicing "partisan tolerance." That is, tolerance of the extreme Left and virulent intolerance of anything else.
