…with some (putative) lessons from German history.  I think the author's basic point is sound–anti-fascist violence in the end helps fascists–but the piece wildly simplifies the dynamics involved in the Nazi rise to power.  As Achen and Bartels document in Democracy for Realists, the big shift to the Nazis occurred in 1932, and occurred almost entirely among Protestant voters disenchanged with the failure of the old Protestant parties to deal with the economic crisis.  And the emergency decrees by which absolute power was seized have a rather more complicated history.
