As Hannah Arendt said in her book The Origins of Totalitarianism totalitarian movements required and received absolute loyalty. A member might have to let himself be tried, found guilty of any crime, cooperate with the authorities, without objection—all in the name of the movement.
Of course, not everyone is able to give such loyalty. As Arendt said,
“Such loyalty can be expected only from the completely isolated human being who, without any other social ties to family, friends, comrades, or even mere acquaintances, derives his sense of having a place in the world only from his belonging to a movement, his membership in the party.”
Notably, that was also the kind of loyalty Trump demanded of the Trumpsters, and usually got. That’s what he told James Comey who refused to give it. It did not take long and Coney was out of his job as Director of the FBI. That happened to countless others.
Arendt found it interesting who was able to give such loyalty. It was surprising. As she said,
“What is more disturbing to our peace of mind than the unconditional loyalty of members of totalitarian movements, and the popular support of totalitarian regimes, is the unquestionable attraction these movements exert on the elite, and not only on the mob elements in society. It would be rash indeed to discount, because of artistic vagaries or scholarly naiveté, the terrifying roster of distinguished men whom totalitarianism can count among its sympathizers, fellow-travelers, and inscribed party members.”
Again Trumpism found similar support among elite conservatives. Trump and Trumpsters expected Mike Pence to overthrow the votes of states despite the fact that courts had refused to do this, and despite the fact that there was no way this could be done and when he refused Trump immediately turned on him even though he had received 4 years of abject loyalty from Pence. And with only the vaguest of suggestions, the Trumpian mob marched to the White House with chants “Hang Mike Pence.” Later. even though his life had been endangered by Trump and his followers at his behest, Pence did not overturn the election results because he thought he could not do that, but after this devotion to the leader was stubbornly persistent
Loyalty is an astonishing thing. Absolute loyalty is incomprehensible. But it is real. It can persist long past what reason would suggest.
