Except the part about the authoritarian regime, the US has many problems but it's still a democracy.
Edit: I'm glad you downvote me because you never had to learn what living in a dictatorship is like, I didn't, but my parents generation still did and I can tell you it looks nothing like the US of today. Women were only allowed to be housewives, groups of more than 2 people couldn't talk openly in the street because that can lead to dangerous ideas spreading out, you would have to be careful what you said even at home because your neighbour could be listening to sell you out, all pieces of art and media would go through an government office to get censored, and so on, so yes, I stand with what I said, the US is a free democratic country even if you have been spoiled enough to think it is not.
