@Cousin_Isobel Gender: An Ethnomethodological Approach (1985)

"Kessler and McKenna convincingly argue that gender is not a reflection of biological reality but rather a social construct that varies across cultures."

So that predates Judith Butler's "Gender Trouble" by five years. And from what I read on Wikipedia, Kessler and McKenna are already leveraging DSD to make their arguments.

Notes from the rabbit hole:
* Left Hand Of Darkness (1969)
* Dialectic of Sex (1970)

Are we just recycling history? When is grunge coming back?
