There is significant crossover / capture of Mormons into that culture. I’m not blaming Mormon culture/theology for this particular type of radical and willful rejection of govt authority, although “we” naturally have a lot of skepticism of govt. in general, for some very obvious reasons when you investigate the history. My implication is that Mormons, whom people keep hoping will break from the Trump fever dream, or the traditional conservative fever dream, will disappoint. There have more recently been statements from top church leaders to tone down the rhetoric and not demonize immigrants, but those directives don’t hold much sway when it comes to the greater culture wars and voting. At least not yet.
My feeling is those statements are solely for outreach / missionary work - tone down the rhetoric to remove barriers to conversion. It's similar to how in one of my more recent conversations with a LDS missionary he stressed that the LDS church is totally ok with gays (provided you don't act on it).
I disagreed with him and had many examples. He even mentioned, sadly enough, that one of his gay Mormon friends had just committed suicide, which really solidified the point I was making.
