Serious Question...

Can we now dispense with such words as "populist" and "nationalist" when describing contemporary American conservatism and just firmly and confidently settle on describing it as Fascism?

Now, by that I do not mean to try to directly compare Trump to Hitler or Mussolini or that the US will be dominated by Nazis.

I mean has conservatism transitioned to an American version of fascism or a neo-fascist ideology.
