Weird. I wonder why there's a Wikipedia article for something that's "not even a thing"[0].
> It's just a repackaging of Marxist ideals applied to other demographic groupings besides class, and it's just as easily disproven.
Can you cite a single critical theorist who simply transposes class analysis to "other demographic groupings"? The theorists I've read actually stray pretty far from the concept of class conflict, and they do not construct, for example, "gender conflict" or "race conflict" out of the "ideals" such as class conflict. Is there any evidence for your claim at all? Or are you claiming that any analysis of conflict between demographics is simply a repackaging of class conflict?
You fail to recognize the specificity of the idea of class conflict, and why it can't be "repackaged" as an abstraction. As an abstraction, all you're left with is "societal conflict", but nobody would deny that there is some conflict in society of some kind. The concepts of economic exploitation, alienation, historical and current primitive accumulation, base and superstructure, etc. are all core to class conflict analysis, but from what I've read, few if any of these are present in the literature on race and gender.
And while we're on the topic, can you point to which "easy disproofs" you're talking about as they relate to class conflict or "other demographic" conflicts? Ironically, the same critical theorists you claim "aren't a thing" were the same ones to argue against the traditional conception of class conflict (e.g. Marcuse).
