Where do you get nationalist from? You can have socialists who are not nationalists such as Sweden and Denmark and they certainly are not nazis.

It's the flag-waving love it or leave it Republicans that represent the nationalist tendencies in America. Combine that with their unquestioning idea that unelected corporate leaders know best and it becomes clear that the Republicans more closely resemble the sit down shut up and wave the flag anti-intellectual philosophy of the facists.
