In the 1920s, Italian Marxist Antonio Gramsci advanced the idea of using sexual depravity to destroy the nuclear family in order to build a society ready for communism. It was a popular idea among the communist elite. Heck, Hollywood was pushing the limits of probity as early as the 1930s. Gramsci's theories were picked up by prominent German communists of the Frankfurt School. When Hitler kicked them out, they came to Roosevelt's America (his administration was already heavily infested with communist sympathizers) to find high places in the university hierarchy. But the real kicker was when the Marxist educated scions of the Rockefeller fortune funded a sadomasochistic homosexual pedophile, Alfred Kinsey, to redefine "normal" sexual behavior. Armed with the cloak of "science" defined by the psychological profession, foundation-funded lawyers then forced it into schools. Meanwhile, the media simultaneously poured the newly redefined standards of behavior into every home, ad nauseum.
The rest was a matter of time.
