far right

Certainly mid right

authoritarian

Try being left of Biden in a room full of Democrats.

ultranationalist

See above, Dems are resistant to any meaningful change because they believe USA #1. They wave their little equality flag but suggest overhauling a US system and see how quick they become conservative.

centralized autocracy, militarism

Even after a Trump presidency, we can't reign in executive privilege because Dems are just as reliant on it. See: Biden sidestepping Congress to fund Israel, also.....gestures broadly at America for militarism

forcible suppression of opposition

3rd parties have met requirements to be included on ballots and in debates before, dems were just as quick as Repubs to move those goalposts everytime they're met. Also, 2016 - Bernie won the primary, no he didn't shut up also we'll go to court to show our voters they don't mean shit

belief in a natural social hierarchy

I mean, that's just capitalism and Dems are all in on defending that at all costs (See above)

subordination of individual interests for the perceived good of the nation or race

Go to any thread discussing politics or Democratic function IRL and mention any political/social interest other than "Not Trump" or whatever the DNC flavor of the day is and watch how quickly you get told you're a stupid baby. (Case in point, your reply - "You don't have real concerns you just think fascism is anything you don't like nyahhh")

strong regimentation of society and the economy.

Again, capitalism, but politically - Any primary winner would have been rejected for Hillary in 2016 because they just owed her one, and here we are doubling down on Biden for a second term at 81 after 50 years in politics instead of, well, anybody else at all no matter how many people tell them how weak that play is.

Democracy is not shutting out any people supporting things you don’t like.
