Language matters. Fascism is certainly authoritarian but way, way worse than current matters. It waters down the horrors suffered by those who lived under the yoke of it.
Can you define fascism? Only Italian were ruled by fascism per se, but we use the term to described other authoritarian regimes.
Should we wait 50 years and the collapse of democracy to find a new name for this phenomena? Or could this debate be just a diversion?
You can read an essay by Mussolini on the topic here [0], but consider practice vs theory. Fascism is usually cited in reference to Nazi Germany / Fascist Italy, both of aspired towards totalitarianism, featured callous disregard for human life, and possessed collectivist tendencies. Is the US you live in?
The use of fascism here isn't correct as it misses magnitude. Trump's authoritarian tendencies and nationalism is certainly aligned, but falls far short. It's the same way that 'socialism' isn't an appropriate way to describe the policies of Bernie Sanders.
But please continue to abuse language, knowing full well the power of connotation. You'll water them down to meaninglessness.
