You should read the article but to pique your interest here's a brief snippet / summary of what it means:
"Where misogyny enforces the patriarchal gender hierarchy, 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 exactly the nonexistence of people who are neither women (only) nor men (only). […] While misogyny pushes women down into their subordinate place, misandrogyny pushes [gender non-binary and non-conforming] folks out of existence—either by pushing its targets out of literal or social existence or by pushing them into binary gender positions."
