Trump is not a fascist, nor can I think of any Republican in my lifetime who could be considered a fascist. That includes the likes of Joseph McCarthy.
What pop stars like Madonna or actors like De Niro and Penn have to say on the matter is irrelevant. However, shame on the likes of Mark Milley and John Kelly who should know exactly what a fascist is and is not.
A lot of pejoratives may accurately fit Trump, but the term, fascist, is not one of them. At least not so far as I can tell and I loathe the person as he presents himself and his office to the world.
