I think this is where people get quite confused. People point to the illiberal and undemocratic things in liberal democracies as proof of the problems with liberal democracy. But the point is, we have a standard by which we can measure against, that our societies are supposed to live up to. We can point out an example of government censorship, and recognize that's illiberal. The philosophical ideal isn't the problem. The problem is we're not living up to it.
The good news, is we have a bunch of people jumping up and down demanding we do live up to those ideals. And the push back does work, when the voices get loud enough.
So far, those of us who push back and yell, are not being disappeared and sent to re-education camps. Which is a pretty important thing to think about, when idiot libertarians claim we're supposedly living in a totalitarian states now.
