When you take a step back and look at what is happening as a whole, it's definitely not looking good.

I was going to start listing examples but that's not the point now. And even if something specific is undone weeks after because of outcry it's still a steady two steps forward, one step back, progression in a nasty direction.

I've read some books, seen some documentaries, learned some history. What's happening is very obvious and anyone who doesn't also see it is either ignorant or in denial.

I'm not an American so I'm kind of looking at this from the side but I'll try to engage here...

What does "heading in a totalitarian direction" mean in this context exactly?

I'm not trying to use this as a "cherry pick" but this was news from today: "Trump administration reverses abrupt terminations of foreign students’ US visa registrations

DOJ announced the reversal in federal court after weeks of intense scrutiny by courts and dozens of restraining orders issued by judges."

How is this consistent with your theory/hypothesis?

I think what's important is not to look solely at evidence supporting your idea. The important thing is to find things that disprove your idea. That's the scientific method. I.e. finding something that weakens your hypothesis is what you need to look for. If you're not able to find anything at all disproving your theory then we should be really worried but I think there are actually many things going on that are consistent with a functioning democracy. Keep in democracy doesn't necessarily mean acting in ways that you consider to be good. You might think it's crazy to make deep cross cuts in the government but if this is what people voted for then maybe that can play out. Yes, it seems arbitrary and maybe important things are being cut, which is no different than what you'll see when companies do layoffs. But there's also a lot of resilience. At least I don't think it's anti-democratic to run on a platform of reducing government costs and then act on it. If anything the opposite. It might be really bad, but democratic, or it might end up being a good idea. Another example is you probably think it's crazy for the US to abandon Ukraine. I don't like that either but the US government can set foreign policy and it was reasonably clear that's the way they were going to go before the elections. Is this good for the world? I don't think so. Is it anti-democratic. I don't think so either. How will it play out? Who knows.

I would say that Trump is pushing the limits of presidential powers more than others before him. Some of the actions his administration is taking are borderline anti-democratic and borderline legal. But many of them are actually legal and some others will work their way through the courts. Even the Supreme Court which is generally right leaning has rebuked Trump and will likely not blindly side with him.

I'm not a fan of this administration but at least so far it doesn't look like it's the end of democracy in America. That seems like fear mongering. I think the "opposition" would be better off trusting democracy more, highlighting how its policies contrast with the current government policies, the problems it would solve better for Americans compared with the current government etc. This is probably going to end up being better for America's democracy in the long run. The erosion of democracy is partly due to the incessant attacking and divisiveness/polarization. Focus on common ground which I think is actually larger than what most think and trying to let better ideas win vs. being critical of everything is better. Not that you shouldn't speak out against obviously bad actions but it seems we are just 100% focused on attacks.

The US states also have a lot of power. The citizenry have a lot of power. Senate/congress. Courts. I think you guys will be fine but let's see how it goes. To me the bigger risk is the loss of common ground and polarization. If you have half the country basically feeling the other half is the enemy rather than debate policies that's something that can lead to trouble.
