From the outside, it looks an awful lot like the US is sleepwalking into a civil war and the genral populace isn't paying attention.
It becomes normalised, the window shifts, and it has already shifted a lot.
Things that were unthinkable to be done or said by politicians 15 years ago now happen almost daily. Speeches that would be scandals are just another drop in the bucket, rhetoric that would've crashed careers, and get people in absolute shock now became celebrated.
You just have to remember you aren't going crazy, this is not normal and shouldn't be normal, the window just shifted so much that a lot of people learnt to agree with it, for their own reasons, by manipulative tactics.
