The quality needed is not a willingness to compromise but the will to fight things out to a finish

From The Paranoid Style in American Politics by Richard Hofstadter.  Written in 1964 and still useful today.  

Let us know abstract the basic elements in the paranoid style. The central image is that of a vast and sinister conspiracy, a gigantic and yet subtle machinery of influence set in motion to undermine and destroy a way of life. One may object that there are conspiratorial acts in history, and there is nothing paranoid about taking note of them. This is true. All political behavior requires strategy, many strategic acts depend for their effect upon a period of secrecy, and anything that is secret may be described, often with but little exaggeration, as conspiratorial. The distinguishing thing about the paranoid style is not that its exponents see conspiracies or plots here and there in history, but that they regard a “vast” or “gigantic” conspiracy as the motive force in historical events. History is a conspiracy, set in motion by demonic forces of almost transcendent power, and what is felt to be needed to defeat it is not the usual methods of political give-and-take, but an all-out crusade. The paranoid spokesman sees the fate of this conspiracy in apocalyptic terms—he traffics in the birth and death of whole worlds, whole political orders, whole systems of human values. He is always manning the barricades of civilization. He constantly lives at a turning point: it is now or never in organizing resistance to conspiracy. Time is forever just running out. Like religious millenarians, he expresses the anxiety of those who are living through the last days and he is sometimes disposed to set a date for the apocalypse. “Time is running out,” said Welch in 1951. “Evidence is piling up on many sides and from many sources that October 1952 is the fatal month when Stalin will attack.” The apocalypticism of the paranoid style runs dangerously near to hopeless pessimism, but usually stops short of it. Apocalyptic warnings arouse passion and militancy, and strike at susceptibility to similar themes in Christianity. Properly expressed, such warnings serve somewhat the same function as a description of the horrible consequences of sin in a revivalist sermon: they portray that which impends but which may still be avoided. They are a secular and demonic version of adventism.

As a member of the avant-garde who is capable of perceiving the conspiracy before it is fully obvious to an as yet un-aroused public, the paranoid is a militant leader. He does not see social conflict as something to be mediated and compromised, in the manner of the working politician. Since what is at stake is always a conflict between absolute good and absolute evil, the quality needed is not a willingness to compromise but the will to fight things out to a finish. Nothing but complete victory will do. Since the enemy is thought of as being totally evil and totally unappeasable, he must be totally eliminated—if not from the world, at least from the theater of operations to which the paranoid directs his attention. This demand for unqualified victories leads to the formulation of hopelessly demanding and unrealistic goals, and since these goals are not even remotely attainable, failure constantly heightens the paranoid’s frustration. Even partial success leaves him with the same sense of powerlessness with which he began, and this in turn only strengthens his awareness of the vast and terrifying quality of the enemy he opposes.

This enemy is clearly delineated: he is a perfect model of malice, a kind of amoral superman: sinister, ubiquitous, powerful, cruel, sensual, luxury-loving. Unlike the rest of us, the enemy is not caught in the toils of the vast mechanism of history, himself a victim of his past, his desires, his limitations. He is a free, active, demonic agent. He wills, indeed he manufactures, the mechanism of history himself, or deflects the normal course of history in an evil way. He makes crises, starts runs on banks, causes depressions, manufactures disasters, and then enjoys and profits from the misery he has produced. The paranoid’s interpretation of history is in this sense distinctly personal: decisive events are not taken as part of the stream of history, but as the consequences of someone’s will. Very often the enemy is held to possess some especially effective source of power: he controls the press; he directs the public mind through “managed news”; he has unlimited funds; he has a new secret for influencing the mind (brainwashing); he has a special technique for seduction (the Catholic confessional); he is gaining a stranglehold on the educational system.

Striking how many recent "polarizing" events are actually paranoiac delusions.  The Russia Collusion paranoid delusion, the micro-aggressions delusion, the AGW delusion, the false Covid-19 information delusion, etc.  Tightly held beliefs despite the epistemic evidence.  Beliefs bitterly defended.
