When you put it that way, yeah, I can sure see how MAGA was the establishment all along.
Do you want an easy Establishment Litmus Test? Here, go and make two new discord accounts for the server of some game you really like; suck off Biden and tranny cock on one, and on the other just simply gently suggest that you're happy criminals are getting deported. Don't even mention Trump, don't mention MAGA. See how long it takes for each account to get atomized.
This test can be applied in basically any social setting in real life. You can measure how 'establishment' one of these positions is by how much screaming in your ears you get.
