The only place I disagree with you is the idea that MAGA can be described as having this singular united motive at the time.

You have the grifters at the top who know it's bullshit, but who have found a huge pool of the world's easiest marks. You have a lot of genuine believers. You have a lot of people who don't have any beliefs but who simply do as they're told. You have a lot of people who are just trying to fit in. And you have a bunch of little Nazi wannabes who know everybody else is being grifted, but who either simply like hurting other groups of people, or they believe that they'll eventually become the grifters.

With MAGA, like with most political groups, if you want a crowd of specific types, you just have to pick who is in the crowd.
