In addition to the authoritarian aspect pointed out by a sibling comment, the far-right generally consider the ends to justify the means because of their sense of righteousness. They will compromise their values to get what they want (control over others). Just look at the hypocrisy of the free-speech absolutists on twitter who have no complaints over Lonnie shutting down Leftist accounts.
It’s an odd phenomenon called a mass formation in large populations, when groups of people get fixated or obsessed with a certain concept or even a thing that the group ourself becomes self-reinforcing; usually until a point of exhaustion is reached or self-destruction. It can also be effectively injected into a culture as it was in Germany’s case after the war through endless and limitless collective and hereditary blame abuse to the point that Germans generally do not have self-respect, and if they show even a slight bit of self-respect they are branded far right, as of that means anything being the subconscious conditioning people have been subjected to.
It’s kind of sad and unfortunate and humanity should never have allowed the collective torture, abuse, and punishment of Germans even to this day 80 years later. It’s a sick and depraved thing only the most devious and evil people would condone, let alone perpetrate.
We seem to have a general problem with people not understanding that democracies have regular elections and the other party is going to get back in at some point. So then whenever one party is in power, instead of thinking ahead by five minutes and realizing that adding new constraints on the government and adding rather than eroding checks and balances will help you the next time the other team gets in, everybody thinks of them as an impediment to doing whatever they want immediately.
And then like clockwork they get butthurt when they checks they eroded or failed to put into place aren't there after the next election, as if they had nothing to do with it.
