Well, let's look at the facts. 💩 has demonstrated behavior which meets the definition of fascism:
1. Nationalism: His "Make America Great Again" slogan, and his policies of "America uber alles" are alienating our trading partners and military allies.
2. Totalitarianism: He concentrates power by appointing yes-men and cronies in cabinet positions and the judiciary, and with sufficient people in the Senate who are complicit with his crimes, he can break the law without consequence. He already has.
3. Economic caste enforcement: He talks about bringing in jobs while preventing any sort of minimum wage adjustment for cost of living, he taxes the middle classes while giving tax breaks to the wealthy, and ensures that health care makes paupers of anyone who isn't fortunate enough to not get sick.
4. Racism/xenophobia: He's diverting money towards a useless wall which does nothing to stop illegal immigration, and only costs money for construction and maintenance. It's just one big show of force to no avail. He's also built concentration camps for refugees seeking asylum from problems in their home countries that the US created, and banned the travel of muslims from predominantly muslim nations (except for the ones which sent us terrorists). He condones the actions of white supremacist groups, as in Charlottesville, and denounces peaceful protests against unwarranted police brutality as "unpatriotic."
5. Delegitimzation of the legitimate media: Any reports which put him in a less than favorable light are denounced as "fake news," even though they present his own words and actions with video and written evidence. Bias or no bias, real journalism must contain facts, and they do present facts. Meanwhile, 💩 and his ilk accuse the opposition of that which they are guilty.
And he condoned the white supremacist and neo-nazi marchers at Charlottesville:
