Your position has changed many times throughout our discussion, from faulty use of Fisher’s theory, to raving about dominance hierarchies and now you’ve settled on “the theory is outdated”.

The theory is not in fact outdated because it’s based on historical materialism which is widely accepted among academics and has proven itself to be true. In fact dialectical materialism was extrapolated to form the basis of the conflict theory which many sociologists use to explain ‘why’ and ‘how’ conflicts develop in society, like between different races, the patriarchy etc.

There’s an argument to be made that the economic system that is “socialism” is outdated, but that’s another argument; the philosophy underlying it however is not. Every Marxist whether anarchist, Leninist, syndicalist and so on agrees that capitalism will end; everyone’s just arguing about whose type it’s going to be.
