I recently stumbled on the political polarization score [1]. America hereby joined the club with Poland, Turkey, and Belarus. It's an awful club to be in. If you wonder how it looks in real life. Every discussion on history, politics, social issues immediately escalates to "us against them", "you are from among them". On every scandal and corruption the only concern is "are they from us or from them?".
