Claire Graham is a British intersex advocate, and an intersex woman herself. David discusses the new attention given to intersex issues, as they are often used to bolster the claim that sex and gender are not binary. But ‘intersex’ is a misleading term, because almost all cases are quite easily determined to be men and women, and in many cases, such as Claire’s, there are no characteristics of the opposite sex at all, just an abnormal development of the sexual anatomy. Claire has experienced significant hostility from some transgender rights activists, and has been banned on Twitter. Yet other transgender people have supported her, and don’t want the idea of distinct sexes banned.
