A very special group of mainly Jewish immigrants constituted the “Frankfurt School”. These were Marxist “intellectuals” who fled Hitler’s Germany one step ahead of the Gestapo. Painting themselves as the victims of merciless political oppression, the truth is that these men and others like them were largely responsible for the rise of Hitler in the first place by fomenting Communist revolution in Germany. The gullible American people took them in and promptly received their just reward: the Frankfurt School subversives immediately began to sabotage the country that had given them refuge. This tidal wave of Reds soon infiltrated virtually every American institution: universities were an early target but all of the major branches of government, the media, Hollywood and key elements of national life were targeted as well.
