Let's explore this.

Authoritarian. Let's start with this, it's a key word with regards to fascism. How is USA more authoritative than it was under previous presidents? What laws have been passed which limits people's freedom? How is the state exerting more authority than it was?

Dictatorial? Take a look at North Korea. That's a dictatorship. Does anyone in politics or the press challenge the Authority of Kim? If they do, they die. Correct me if I'm wrong, but this is not happening in USA. From where I'm sitting, Trump is relentlessly being challenged. He is not a dictator, again you're incorrectly using powerful words to describe leaders you don't like.

Forcible oppression of opposition... nope. Well, with two notable exceptions... Chelsea and Julian.

Regimentation? That's strict control of behaviour. North Korea, not USA.

Ultranationalism... maybe this box is ticked, but it's the only one.

Trump is not a fascist.
