If we were to apply the approach the Left takes in this country (and most other countries to be sure) and apply it to an individual, that individual, when he or she finds out that he or she has evil in them, would kill themselves. They would ignore the good in them, focus solely on the evil in them, and seeing it, loathe themselves beyond any possibility of redemption.
We all have unprocessed trauma, which looks like evil, which looks like darkness. It is inchoate rage, destructiveness, cruelty, vindictiveness. It’s in all of us, to some greater or lesser degree. Those who say they have none, that they feel malice towards none, are either saints, liars, or most likely dissociated from the full range of their own emotions. We hide the bad stuff, from others as well as from ourselves.
But combining the analogies, I would suggest that most Leftists are psychologically dissociated people. They are emotionally weak and unintelligent. That is why they are Leftists. They seek revenge on the world in the name of the Good, the Just and the Beautiful. They are the latest iteration of the sorts of people who used to run the Church, understood generally. People were tortured and killed “for their own good”.
[I suppose, actually, that Communism is little but the spirit of the Inquisition brought forward by atheists in support, purportedly, of an Earthly salvation for society at large. This makes it a worse lie, since we can see what they did. None of us can see what happened to the members of the Church in Heaven.]
But emotionally intelligent people can see both the good and the bad at the same time, place them on a continuum, and consciously reject the bad while preserving and improving the good. That is the process of growth.
The spirit of radicalism is the spirit of KILLING the bad, destroying it, rooting it out, humbling it, abasing it, and then murdering it.
Would you do that to yourself? Would that be a way to deal with your own Shadow? If you chose that path, it would be one of severe mental illness, and as I say, probably suicide.
So I would suggest that most of these people are projecting their own Shadows onto America and “Capitalism” as a whole. Everything they hate about themselves is what they see in Corporate America, and Donald Trump, and white people. So they attack those things as well as they can, in a spirit of self mutilation.
