So not seeing a huge difference between liberal democracies and authoritarians.
At what point does it become authoritarian to you?
They even put lawyers defending these politicians in prison for defending them... The constitution doesn't seem to matter since the government apparently don't have to care about it.
Your question deserves an answer.
The US was a liberal (post-Enlightenment) democracy.
Senator McCarthy was eventually kicked out of Congress for his witch hunt.
President Nixon was confronted by Republican members of Congress, and he resigned after this meeting rather than face impeachment.
So when I was a kid, lawmakers largely upheld the norms, the rule of law. Many of those same lawmakers might have today been considered racist or misogynist or might have failed some other standard of 21st century society.
As a liberal democracy, the United States has never been perfect, but it's always been worth improving.
I think lot of people I know would feel concerned about what might happen to them if they did that right about now. I don't pretend to know anything about you, but it might be worth examining whether the level of concern you expect people would have about this might vary quite between people with different circumstances than yours. At least to me, it seems pretty likely that if a country were to slide into authoritarianism, not everyone would feel the effects equally all at once, so the fact that you haven't felt a change in your level of concern about this doesn't necessarily mean that a shift isn't happening.
To be clear, I'm definitively not saying that it's impossible for anyone to know whether it's happening or not because we can't know the experience of literally everyone, or that I'm 100% positive what we're experiencing will end up in undeniable strict authoritarianism for everyone. My point is that I do think there's been a genuine shift in how safe a large number of people feel from persecution in the past year and a half that's based on things happening to them or people in similar circumstances to them. It's certainly possible that I'm in a bubble where I'm associating with a lot more people than average who have these concerns, but the reverse is equally true for someone who hasn't been noticing these things, and I do think there's sufficient evidence that the concerns are real. The implicit assumption that everyone feels equally comfortable in their rights protecting them just isn't something that seems accurate right now.
don't be ridiculous there are anti-trump protests every single day. Even on Labor Day (last Monday).
I would not be disappeared. I would not be charged with a felony. I would not be imprisoned for years or decades.
And, where the rubber meets the road for my personal mental health: I can say what I think to my friends and family. They may disagree. They may even argue. They're not going to report me to the secret police, nor are there secret police waiting for someone to report something.
That distinction really matters.
This is very different from what things are like in places like Russia.
