Relates to postmodernism. But there is interesting distinction in the definition of postmodernism?- of it not so much being an ideology of some kind, and more a description of the state of the world. And people like Deleuze & Guattari, Baudrillard, are describing that state of the world and what it means, but they're not "postmodernists". They're best described as post-structuralists (Revolutionary Left Radio: Post-Structuralism, Postmodernism, and… Metamodernism?).
Potentially a bit of a linkage between post-structuralism and anarchism and horizontalism (Revolutionary Left Radio: Post-Structuralism, Postmodernism, and… Metamodernism?)
And maybe some tension between post-structuralism and Marxism, in its presentation of a scientific approach to history (Revolutionary Left Radio: Post-Structuralism, Postmodernism, and… Metamodernism?).
absence or refusal of a general political theory has led some critics to accuse the post-structuralists of a self-defeating normative relativism or outright nihilism.
The critique of representation is a central theme of the post-structuralists; Deleuze once told Foucault “you were the first…to teach us something absolutely fundamental: the indignity of speaking for others.”
