This paper develops an account of misandrogyny that is modeled on Kate Manne’s account of misogyny. On Manne’s view, misogyny is a system of mechanisms that together police and enforce the gendered hierarchy of a patriarchal order. On the account developed here, misandrogyny is a system of mechanisms that together police and enforce the gender binary of a patriarchal order. The gender binary is constituted by norms that preclude the existence of persons who aren’t consistently ‘read’ either as a man (...) (and only a man) or as a woman (and only a woman). Misandrogyny thus polices and enforces the nonexistence of people who are neither women (only) nor men (only). After some clarifying preliminaries, section 1 describes mechanisms of misandrogyny that push individuals into specific binary gender positions; section 2 describes structures and institutions that compel gender non-conforming people to assimilate to the gender binary; section 3 describes mechanisms that target gender non-conforming persons for fatal violence.
