Pretty much the opposite of libertarian, IIRC.

There's this weird thing where libertarians go so far right they become neoreactionaries, and vice versa. It's sort of the horseshoe theory for the authoritarian-libertarian spectrum I guess. I don't really understand it.

Frustration, I'd guess. They look long and hard at one ultimate solution to the problem of human governance, finally realize it won't work, then swing to the opposite conclusion to examine it.
