“Fascism: a political philosophy, movement, or regime (such as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition”

That seems pretty on point to Trump, most things he says follow those lines. He likes Putin, he wanted to have all the power/authority not just over the exec branch, clearly is racist, says racist things, and does racist things. Loves wealth inequality and supporting policies that increase the wage/income gap and reduce law enforcement against the wealthy/increase it on the poor, chose supreme court justices that would force social norms onto people against their will. If he had his way, he’d absolutely love to be the head of an autocracy.

Maybe some of my points are stretching it, but that last one is pretty much all that’s needed. The term Fascist isn’t automatically Hitler, just like conservative isn’t automatically Hitler.
