Over the years I have come to form a vague but persistent conviction that there's a distinct analogy between reactionary ideologies and certain mathematical constructs.
To the true believer of (say) "ethnonationalism", their ideology must surely make sense in their head, feeling as sound and whole and true as a mathematician's appreciation of a complicated proof. It's been a long time since I've worked complex mathematical problems but I'm aware of the clear cold feeling of truth that comes with successfully working out a difficult exercise. It's like a sudden gust of wind from a high snowy mountaintop, or like the pleasurable sting of being hit in the face with cold water on a hot day. One feels, for a moment, as if illuminated by starlight. I have no doubt that all the fascist ideologues I've seen scurrying around on Twitter, with names like "TheSensibleCentrist" and "Apollonius of Fresno", or the ones who proudly advertise a long string of memberships in "non-political" think tanks, all believe they've experienced this same brisk, bracing feeling of uncovering a deep truth. They must feel like their ideas make sense.
And I think perhaps they do make sense, but in the same way that a Klein bottle makes sense, or the way that one can find solutions for otherwise impossible mathematical problems among the complex numbers, i.e. numbers that have no physical representation. "Imaginary numbers" excited my imagination (hah) as few other intellectual concepts did, when I was a child learning mathematics. Aha! negative numbers do have square roots! So they do, but a "real" square root may be constructed with a compass and straightedge, while an imaginary root can only be represented symbolically. The real root of a function is a dot on a graph; the imaginary root isn't to be seen on the graph at all and must be obtained through symbolic manipulation. Not all mathematical entities, even if they can be logically defined and manipulated as readily as ordinary numbers, have no concrete form. One can't assemble -5 + i√2 beans in one place.
Hence I conjecture that extremist ideologies of all sorts, not just right-wing ones, must have some equivalence to such virtual constructs in mathematics. They can be defined and discussed, but they can't ever be realized in the material world, any more than one can construct a real Klein bottle, only an approximation or lookalike to one. In the heads of the "gender critics", for example, their ideas must make perfect sense and seem like the only logical ones. They measure the rationality of the world against their bizarrely contorted (but logically consistent) hypotheses, find that the world doesn't measure up, and blame the world for not being real enough. They would like to codify their ideas in a fully rational and concrete form, because then it would be persuasive. They can't ever get it quite right but no matter, they'll keep trying the way that people are still trying to "trisect the angle".
The example of the Klein bottle is especially useful here, for the difficulty with building Klein bottles and many other such mathematical surfaces is that they require "self-intersection" in three dimensions. If we could somehow imagine two wholly separate pieces of matter occupying the same space at once, as if they could pass harmlessly through each other, then you could make a genuine Klein bottle, but real-life matter does not behave that way. One sees something like "self-intersection" happening with fascist ideologies. Consider the "doublethink" involved in the infamous TERF slogan, "Sex is Real", which seems like mere tautology. The slogan works for them because of "self-intersection". The word "Sex" is carrying a heavy load of multiple meanings. They wish outsiders to see "Sex" and think of real-world things—sexual things. But they also wish "Sex" to mean something subtle and insidious and indeed metaphysical, referring to their absurd desire to enforce the "laws of biology" through coercion and violence.
Can this be formalized somehow? The analogy between harmful ideology and abstract mathematical constructs seems so natural that I'm persuaded to believe that it's valid and can be thrashed out in some practical form.
