Abstract
Due to the recent changes in federal regulations about gender equity in education in the USA, some policy makers have resurrected single‐sex public education. Because single‐sex schooling ignores the complexity of sex, gender, and sexuality, it sets up a ‘separate but equal’ system that is anything but. Discounting the ways in which gender is negotiated, constructed, and performed, and the variability of anatomical sex, current arguments for single‐sex schooling reify the false binaries of sex and gender, rely on assumptions of heteronormativity and, in turn, negate the existence of multiple sexes, genders, and sexual orientations.
