America wasn't fascist, it had fascism. For example in the form of McCarthyism. I don't support Marxism or Communism. I just think the ruthless persecution, group think powered selective reading of the constitution and bullying tactics of empowered individuals constitute to enough of the qualities to be labeled fascism.

If you've got a scale that goes from equal rights direct democracy on the left to dictatorial fascism on the right, then America was not quite fascist in the sense that they still had indirect partly represented democracy. But the way minorities, other-gendered, other-lifestyled and the politically deviant were denied representation and other basic rights it was definitely on the fascist side of the spectrum.
