I believe that Trump can only be understood by understanding self hate. My understanding of self hate goes like this:
We were all put down as children, made to feel the worst in the world and the only way we survived that was by developing a protective ego. The ego is our false construction, identification with something external on which we hang a new substitute sense of self worth. The ego protects us from the pain we would feel if we got in touch with out true feelings, that we are actually worthless. But those feelings are a lie. There is nothing wrong with us. And we would know that if we were capable of suffering, of remembering our original humiliation. Thus it is that while the ego saved us from childhood despair, it now prevents us from knowing our real inner truth, the one thing and the only way we can return to real mental health, to feel what we really feel and see it was all a lie we had to buy into to survive. Now, the secret and the mystery of our condition, then, is that we desire to be whole again, that we want to return to our original state of unity and joy to be alive, but we can't do it consciously because we fear the pain it would bring. The result is that our self hate becomes an unconscious desire to destroy ourselves, to break our ego attachment by real world fuck up and failure. We see this all the time with men of power and respect who do something like get a blow job from a intern and have it come out on a blue dress.
Slowly but surely, I think, Trump is also trying to cure his narcissism by taking it to unsustainable limits. He is trying unconsciously to destroy himself.
The problem, of course, is that because he is unaware of what is happening, he does this in a way that is dangerous to all Americans. My personal feeling is that this unconscious destructiveness is coming to a head, that he may be simply too obviously dangerous to be allowed to continue to simply ruin himself, too dangerous that is to people with the power to stop him. I would much rather he destroy himself on his own by becoming too preposterously insane for the house and senate to continue to sit on their asses and they finally act to impeach him. It is what he wants to happen, I think.
