The idiocy in the German populace that I'm referring to was the state of the Weimar Republic prior to Hitler gaining the Chancellorship. It's written all over that constitution, and the political fracturing in the Reichstag: the envy and resentment of the capitalist West, the paranoia in the form of anti-Semitism, the superstitious reverence for both the Prussian and Protestant traditions, and the egalitarian current that brought them all to fascism in the form of a nationalistic socialism. Hitler was the face of the common denominator that transcended party lines, and that face belonged to a spiteful, delusional mediocrity.
