At which point might as well elect competent representatives then lol

You're describing something very deep, while only touching the surface.

On the left, people are not very forgiving of other leftists, when they cross the line. And if you really cross the line, then we just don't want you on our team anymore, gtfo.

On the right, it's like no matter what you've done, as long as you fight for the same thing as the others, you can still be on the team. This is why you see artists make a shift to the right, just before a big scandal, they know they will still have a fangroup as long as they share rightwing propoganda.

This is great for the right wing in the short term, but eventually the techbros and the christofascists, and the Nazis will all realize that they don't really have anything in common, except a desire to rule everything. "But not like that, like this!"

It's gonna be interesting to see the showdown between all the different fascist groups Trump has under his flag.
