Lauren Berlant was a U of Chicago literature professor and a scourge of establishments wherever she found them. Including within the worlds she inhabited: feminism, Marxism, queer studies. I always appreciated this kind of insight:
Berlant tried to show how claims to unity on the part of the feminist movement are invariably accompanied by complaints from those who felt excluded. Berlant cast doubt on conventional ways of positing social and cultural unity, asking at what price such unity is achieved, and whether it unwittingly relies on mechanisms of hierarchy and exclusion.
Berlant extended this critique to nationalism and to all movements that employed its language, like talk of a Queer Nation. Nationalism, Berlant wrote, always ends up involving "sacrifice, stigmatization, and dispossession." You can believe that your nation, tribe, corporation, political party, or social movement will support and nurture you only by deluding yourself: "All attachment is optimistic."
Berlant held a lot of opinions that make no sense to me, but she had a feeling about groups that I very much share.
