Right-wing pagans like Bronze Age Pervert (and, for that matter, Trump) reject both Christian metaphysics and ethics. As such, they are unlikely allies of reactionary Christians. And yet, the alliance exists; if you don’t believe it, look at the pictures of the 1/6 rioters, with QAnon supporters standing next to people with hats and signs equating Trump with Jesus. How can this be?
They have a common enemy–liberal democracy–and they want to burn it down. Trump is their instrument of choice. They’ll deal with what happens next after the great national institutional bonfire.
This won’t end well for either party to the unholy bargain. The fact is that the wannabe theocrats are ideologically closer to the liberal democrats, who at least accept Christian ethics, than to people like BAP. The sooner they come to realize it, the better.
