People who don't like Trump are so opposed to him that they hate on his followers. [...] I never saw it with Obama.
I think the very fact that you refer to people who approve of President Trump as his
followers shows that you know, on some level, that there's a problem. Nobody attacked Obama's followers because
Obama did not have followers.
Obama didn't hold political rallies outside of election season. He didn't (for the most part) use his position to interfere in the operations of businesses and institutions which were not supposed to be under his purview (such as the NFL). He didn't sell political symbols for people to wear on their heads to signal support for him. The propaganda techniques that Donald Trump uses are bad for society. More importantly, Trump's political-brand-techniques are the kind of thing that politicians around the world agreed to stop doing after 1945 (in the West; 1953 in the East), because they saw how dangerous it could be. Trump does something that Hitler and Stalin were known for, and that Hugo Chavez used to great effect: he tries to cultivate the emotions and sympathies of his supporters. He drums up rage in a way that politicians are simply not supposed to do.
For that matter, Trump also spends a lot of time and energy telling his supporters that other people hate them. It's a typical isolating tactic that cults use. The very claim, "people hate me for being a Donald Trump supporter",
is precisely what Donald Trump wants you to believe. Can't you see that?
Is he a fascist? I don't care about the classifications. Classifications are a way of telling bedtime stories. The important things about Donald Trump are the things he says and does, of which some are okay, most are mediocre, but a handful are truly awful.
Here's something that's not a classification: Trump spreads lies (the incidence of voter fraud) among his supporters to justify anti-democratic policies (voter registration rules that disenfranchise voters). This includes laws that have seen the Supreme Court, e.g.
Brakebill v. Jaeger. Even if it's not a violation of the Constitution, the fact that it is
nearly a violation of the Constitution should bother you because it is
already based on a lie. Previous voter fraud protections were fine and the incidence of voter fraud has been very low.
I don't have to argue about whether that's fascism, I just know that I draw the line somewhere before that. Manipulating elections is not okay.
