I think you can be a "fascist" either way.  Communism is an economic theory.  Fascism is a system of governance.  The economic system of a nation can be anything, as long as the Fascist goals and dictates of the leaders (Oligarchs or Politburo) are followed. The stock in trade of Fascists is Brutal Force.  It is a tool that Communists are clever at adapting to their own needs while vilifying it in non-communists.
