No, Trump is NOT a fascist trying to become dictator of the US. The explanation is far more mundane.

12. I still think he's enough of a fascist pig to call him a fascist pig.

But, this article agrees with you:

How fascist is Donald Trump? There’s actually a formula for that.
Grading the billionaire on the 11 attributes of fascism.

Fascism was born in Italy during World War I and came to power with the ex-journalist and war veteran Benito Mussolini in 1922. Since the 1950s, dozens of top historians and political scientists have put fascism, especially the Italian and German versions, under the microscope. They’ve come up with a pretty solid agreement on what it is, both as a political ideology and as a political movement, factoring in all the (sometimes contradictory) things its progenitors said as they ascended to power. As a political ideology, fascism has eight main traits. As a political movement, it has three more. So: Just how fascist is Trump? On the fascist meter, we can award him zero to four “Benitos.”

They rate him on the following:

1. Hyper-nationalism.

2. Militarism.

3. Glorification of violence and readiness to use it in politics.

4. Fetishization of youth.

5. Fetishization of masculinity.

6. Leader cult.

7. Lost-golden-age syndrome.

8. Self-definition by opposition.

9. Mass mobilization and mass party.

10. Hierarchical party structure and tendency to purge the disloyal.

11. Theatricality.

See the article for the individual scores they give.

Add all this up, and you get 26 out of a possible 44 Benitos. In the fascist derby, Trump is a loser. Even Spain’s Francisco Franco and Portugal’s António de Oliveira Salazar might score higher. While there is a strong family resemblance, and with some features an uncanny likeness, Trump doesn’t fit the profile so well on those points where the use of violence is required. Projecting an air of menace at rallies, uttering ambiguous calls for assassinations, tacitly endorsing the roughing-up of protesters, urging the killing of terrorists’ families and whatever else Trump does — while shocking by the standards of American politics — fall far short of the genuinely murderous violence endorsed and unleashed by authentic fascists.

In a more nuanced approach, we might weight the various traits of fascism differently, but it’s not obvious how best to do so. Hyper-nationalism, for example, is more consequential than the youth fetish and perhaps ought to be taken more seriously. But it is also less distinctively fascist, being common to many types of political regimes. A longer list, too, might add refinement and complexity. But Trump does not do nuance. A crude, quick and flippant assessment is what he deserves. He is semi-fascist: more fascist than any successful American politician yet, and the most dangerous threat to pluralist democracy in this country in more than a century, but — thank our stars — an amateurish imitation of the real thing.
