Warhammer 40k came out of the same circles of comic artist nerds as Judge Dredd, and very much always embodied the same sort of left-lib brainrot where they're satirizing fascists and shitty government policy and all, but then turn around and whinge about communists and just unironically do fascist fearmongering about communist invasions and fifth columns and shit, like the Judge Dredd authors did with the Apocalypse War arc.

Like Warhammer 40k is at its core Dune and Judge Dredd and Tolkien all squished together and then inflated into something absurd and grotesque, as a joke. And then on top of that is 40 some years of different authors and artists painting it with coats of "trying to do real serious grown up worldbuilding in the silly space game world" until what's left is something weird and entirely incoherent.
