If queer theory destabilizes identity categories, how does it account for the political need to preserve some of their boundaries?
I’ve been thinking about a tension between queer theory’s critique of fixed or naturalized identity categories and the fact that those categories can still have real political and social functions.
Take “lesbian,” for example, queer theory gives us plenty of tools for questioning whether categories like lesbian, gay, woman, etc.. are internally coherent or historically stable. But lesbian also names a particular sexual orientation, history, community, and set of experiences.
So how does queer theory distinguish between destabilizing a category and making that category so porous that it stops describing anything in particular?
Is there a serious theoretical account of when boundaries are politically useful or necessary, even if we accept that the categories themselves are historically contingent?
I’m especially interested in writers who engage directly with this tension, or any work that explores it in depth.
