I think you're on to the right approach. Trump himself has of course exacerbated existing fear and added new ones, and has done so intentionally to offer himself as the solution to this fear. That one is obvious. But there are other sources of fear. So what do you think we fear?
Let me begin by saying that while I think I know what we fear, that knowledge does not mean I have personally transcended that fear. I am just a nobody who maybe has had some atypical experiences. I used to feel utter black hopelessness and it drove me mercilessly to question why and seek answers to that question. I experienced something that put that all to bed. Then I met somebody who I was sure had gone very much farther than I had, a psychoanalyst who had had more analysis himself, he said, than anybody else and in the process discovered that he hated himself and that this is a universal condition, one I also confirmed. He, however, was as he said, 99.999% sure he had transcended via reliving his entire traumatic past. All I can say is that he was like nobody else I have ever met.
Anyway a lot of what I know I learned from him. That is why I would say that what we really fear above all else is to experience love because we feel, were made to feel, we do not deserve it. We were made to hate ourselves as children, instead, by being put down as children, we were psychically murdered, and it was our openness and love that made us vulnerable to that. We are determined to never let that happen again.
The form which that resistance takes is ego and competitiveness. We are driven to be better than others in any way we can because it helps to mask our feelings of worthlessness.
In America, we have make our disease a national occupation, competing with others and wining. That is who Trump says he is, a winner who can make America great again. He offers what we crave, to be on a wining team so we can deny the real truth of what we feel, that we are worthless, that we deserve nothing.
I am sorry the truth is so bleak, but we will never get past it without facing the facts. In our desire to deny what we feel, we are all conservatives driven by deep emotional terror.
This is the general situation. It manifests in every aspect of out lives only some of which are political.
