re: What changed political views and the animosity of parties so much in 2000?

The woke left. They’ve continuously gotten more and more ridiculous and gone so far left the last 10 years with impunity. It’s almost like they just wanted to see how much they could get away with. On the right, if you go too far right, you get in trouble. You get cancelled, etc. And you sure as hell don’t control the narrative. There hasn’t been much of a consequence on the left to this point, but I think the Israel / Palestine thing of all things is changing the tides a bit. The Claudine Gay thing basically turned DEI on its head. That, and Elon owning X, along with guys like Joe Rogan and Bill Maher speaking up, those guys all being traditional Democrats but being called “far right nut jobs” by a LOT of folks on the left.
