 The positions outlined above share an underlying metaphysical perspective on gender: gender  realism.[2]  That is, women as a group are assumed to share some characteristic feature, experience, common condition or criterion that defines their gender and the possession of which makes some individuals women (as opposed to, say, men). All women are thought to differ from all men in this respect (or respects). For example, MacKinnon thought that being treated in sexually objectifying ways is the common condition that defines women’s gender and what women as women share. All women differ from all men in this respect. Further, pointing out females who are not sexually objectified does not provide a counterexample to MacKinnon’s view. Being sexually objectified is constitutive of being a woman; a female who escapes sexual objectification, then, would not count as a woman.
