Nazi metaphors have become far too overused. To the Left, everything to the right of Chairman Mao Zedong is fascism. Such overuse of Nazi imagery is disrespectful to the unique evil of the Holocaust. It should stop.

Still, a more modern and exact analogy can be applied to the modern American Left. It is the Stasi, the feared German secret police that terrorized East Germany from 1945 to the fall of the Berlin Wall.
