I think that is the thing they all seem to have in common. Anger, fear, and bitterness. They are afraid of change to the point of being willing to risk everything to not have to. I think that comes from insecurity.
People have different tolerances for cultural change, and some of that variance is due to inherent personality differences rather than life experience. But regardless of the root cause of that alarm, I've always thought that "Future Shock" had some good insight into the effect of rapid change on a society.
We're seeing a lot of people who simply can't cope with the values and morals of their world turned upside down. They ARE angry, fearful and bitter. The world is changing around them, despite their best efforts to hold on to the past. They are bombarded with radically different sources of "truth" and can't process so much information that counters their own sense of reality.
Some people are well-educated and just in emotional shock, but the impact on people without much education is much worse. They don't have the context to understand or judge the quality of information they're receiving. They believe their local preacher or FOX News without question because they quite literally can't make sense of the world around them and they are incapable of critical thought.
I'm related to people like that (on my father's side). They were raised in a small town in East Texas, without even finishing high school. They are marginally literate, barely holding together their lives financially, and deeply embedded in the prosperity gospel of Evangelical Christians. Their view of the world outside their town is fuzzy at best. They don't understand how most of the world works, and have no idea of how little they know. Change only increases the emotional pressures of coping.
