I'd caution using what people say on social media as any kind of accurate barometer of what's out there. There are some stories out there about how these fringe movements have used some coding tricks to essentially put their message on auto-pilot. Those comment boards are filled with trolls and a variety of other issues that just make their reliability to form opinions on the quantity of people out there pretty dubious. But yes, rural america feels forgotten. They're independent people that want to be self-sustaining, there is racism in the mix, but mostly it's just contempt for being so frequently the butt of jokes, shamed by both sides, and largely forgotten by both sides. That's going to build resentment.
