Can't be emphasized enough, really. And it's not just the polarization, it's the chicken little nature of it. Everything is a catastrophe, everything is leading to an apocalypse.It's a standard feature of theocracies, and politics is now a religion for many in America. You alluded to the effect when you mentioned it being the national pastime for Puerto Rico. I wonder what gets higher Nielsens here these days: the World Series, or the State of the Union address.
And if you're in the middle somewhere, and criticize a political party for their genuine blunders, or other valid concerns, you are either a 'libtard' and a Leninist, or you're 'MAGA' and 'fascist'. There is no middle ground anymore.
