Honestly I think it's because it's dogma. It's using language to obfuscate rather than reveal. Repeating things that leftists say to one another which they all agree on but no one ever manages to articulate exactly what they mean.
That's the conclusion I've reached as well. It's a milder form of what reaches its pinnacle with people like Butler, but you have the same problem that you can't pin down the definitions to the point you can actually identify an argument well enough to counter it.
Clearly it feels meaningful to the person saying it, but it's not clear the meaning can be successfully conveyed to someone else, at least not in concrete terms. Certainly as a feeling, or mood, or an essence, but not something objective, rather than abstract.
Latest issue of Helen Joyce's newsletter actually touches on some of this stuff. Paywalled, sorry, but an excerpt:
But that first editor was right: what the hell does it mean? Are queer theorists simply saying that “nothing means anything”, or “everything good is really bad”? Is their point to do with the difficulties of definition or the difficulties of action, or both? Are they nihilists or are they cynics? Or is the point something else entirely?
I often re-read “The Professor of Parody” when my rage at the sheer futility of much of what now calls itself feminism bubbles over. This wonderful essay by philosopher Martha Nussbaum excoriating Judith Butler was written in 1999, but reads like Nussbaum had a crystal ball that allowed her to see the dire state of mainstream feminism today. If you haven’t already read it, I urge you to do so.
She writes:
> “Feminist thinkers of the new symbolic type would appear to believe that the way to do feminist politics is to use words in a subversive way, in academic publications of lofty obscurity and disdainful abstractness. These symbolic gestures, it is believed, are themselves a form of political resistance; and so one need not engage with messy things such as legislatures and movements in order to act daringly.”
I couldn’t agree more that the point of activism should be to make life perceptibly better for people who are getting a raw deal—not to provide fancy redefinitions, or justifications for doing nothing. But I’m also someone who has a pretty high tolerance for abstruse definitions, and for “academic publications of lofty obscurity and disdainful abstractness”. So what is it that bothers me so much about this particular sort of lofty obscurity and disdainful abstractness?
I think it’s that it’s not just obscure and abstract; it’s uselessly so. And I don’t mean in terms of the activism it does or doesn’t support; I mean on its own terms.
Forgive me for a somewhat lengthy detour into my long-ago degrees in mathematics. [...]
