Although a thorough-going Germanophile who believed that the truth could only be spoken in German, Heidegger was nobody's ass-kisser. He made a tremendous and largely incomprehensible mistake, but so did Knut Hamsun in Norway and Miguel de Unamuno in backing the Royalists in Spain. The list of Germanophiles was long and illustrious, including the Windsors, who are German descendants, of whom the Duke of Windor was perilously close to treason, H. L. Mencken, whose reservations about the British and French were political and economic, Charles Lindbergh, whose activities in the German-American Bund were frankly seditious stepping on the edge of treason, and Joseph Kennedy when he was Ambassidor to England, who was suspected strongly by Will Bill Stevenson of supplying diplomatic secrets to the Nazis. Anti-semitism was rife in Europe in the run-up to WWII, fueled among the elite in part by the New York merchant banking firm of Kuhn, Loeb & Co bankrolling the Bolsheviks through the Rothschilds. Coco Chanel was a Nazi operator, and the list goes on and on.

Heidegger made an unbelievable mistake but it was not because he learned the goose-step.
