Does anybody know if there exists any reliable research on the religious affiliations or beliefs of qanon followers?
Right now I am making the neutral assumption that they generally reflect the population from which they are drawn. Is there evidence or reason to think otherwise?
I think that's a safe bet. One thing I always try to keep in mind when looking at these kinds of groups or the general situation in America is that most of us are products of the same culture, the same religion, the same influences, the same media, the same educational system, and basically the same ideals, mannerisms, social perceptions, etc. Sure, there are shades of difference and regional sub-cultures, along with sharp differences in class and social strata.
The problem I see with a lot of analyses out there is that they often start with the conclusion that all of these people (Q-Anon, Trump supporters, and other such "deplorables") were somehow spawned or hatched and came crawling out from under a rock. And then they try to come up with reasons to support their pre-ordained conclusion. There's no genuine desire to look beyond the surface, so it's easy to conclude that these people are all a bunch of defective human beings. Because there's no possibility that any of these ideas could have come from true Americans. America is a land of saints, and there's no possibility that any ideas relating to racism, ethnocentrism, xenophobia, militarism, religious fanaticism, or nationalism could have ever emanated from America. We're just too good for that. So, therefore, it's all the Russians' fault.
What religion do they all follow? American patriotism, the closest thing to an official state religion we have in the U.S. The entire argument at hand is "who is more orthodox" in terms of American patriotism. Who loves America more? When you cut away all the BS, legalese, and rhetoric, that's what the real argument is all about.
