Yep. Thanks for pointing that out. None of this happened by accident. In particular, Alfred Willi Rudolf "Rudi" Dutschke who advocated a "long march through the institutions of power" to create radical change from within government and society by becoming an integral part of the machinery.
This was an idea he took up from his interpretation of Antonio Gramsci and the Frankfurt School of Critical Theory.Now we have openly socialist and outright communist anti-American Democrats.
