I've got a simpler version of your theory: Propitiation. Trump couldn't care less about anything but himself. He realizes that to survive this he has to propitiate to Republicans so he kisses their asses by agreeing to do anything they want policy-wise. The only exception to this is trade, which he does to propitiate to his base. Meanwhile, Trump puts on his cowardly bullying tough-guy image, destroying everything civil that crosses his path and Republicans groan and grimace behind closed doors and publicly applaud Trump.It’s simple. You guys elected the most unfit candidate to ever occupy the White House. And even after it continues to be painfully clear that he’s way in over his head (among other things), you continue to find ways to justify support for him. Because some of the policies you like are enacted- the hell with everything else.
The Trump supporting right (making a distinction from “old school republicans”) is united in a few things. The thing that Rock is referencing is the phenomenon of “owning the libs”. I’ve seen it a LOT on the right, and it drives the behavior many of the Trump supporters. Never mind that they know deep down that what they are doing is out of bounds- all that matters is that a “lib” is pissed off by their actions (see Stephen Miller as a classic example of this).
On a basic level, it’s a combination of white privileged folks feeling threatened, and emotional immaturity.
If you can’t acknowlegde that is out there, you’re either too tribal to notice or you’re not paying attention.
Note that some on the left are like this also- but there are far many more on the right at this moment in time.
Propitiation all the way around and it's the most emasculated behavior I've ever seen by a political party, to a man.
