To be honest the most interesting thing to me is the US media. I don't think it has ever been so openly hostile towards one party and so hungry to cause a civil war. They're not even hiding it any more. They're operating as if the country were at war against the Republican Party and any person who is not a card-carrying Democrat must be eliminated, de-platformed, or represented in the most farcical way possible. It's incredible. It's the stuff that totalitarian states struggle to achieve, yet it seems to have happened "organically" in the US.
If I were a hostile actor I wouldn't even need to mount propaganda or spend money on my own content - I would just need to amplify the US media's message.
