SCOTUS is democratic because the guy who was president 30 years ago got to make a lifetime appointment of a supreme court justice that makes decisions that affect people who weren't even alive when they were appointed? You have an extremely low bar for what counts as "democratic." If your standards are that low, you could even argue that because most people in Iran are Twelver Shia and the Ayatollah is the leader of Twelver Shiism, that's democracy.

Again, every single state will prosecute destabilizing behavior. Press freedom is gonna be better in wealthy western countries because a few bad news stories don't destabilize the country the way they do in the developing world. As I pointed out, the way the US reacted to events that actually do have the potential to destabilize the country shows that it is exactly the same as the so-called "authoritarian regimes" and this is also true of liberal European countries.
