The twenty-first century has seen wider acknowledgment of the fact that human sexuality is much more complex than the rigid and unchanging categories… - Shon Faye

Trans feminists seek to interrogate society’s ingrained assumptions about the social and cultural meanings we ascribe to biology. They also generally incorporate an analysis of intersex people, who do not fit this reductive model, and who have suffered historical and ongoing mistreatment at the hands of a medical establishment obsessed with imposing binary biological sex on to bodies that don’t ‘fit’. The experiences of trans and intersex people show us that not all humans fit perfectly into two clear-cut categories of biological sex; indeed, the belief there are two separate sex categories is itself an erasure of sex variations that occur either naturally or through medical modification. The global dominance of men over women can never be dismantled while simultaneously maintaining, preserving and reinforcing the binary model of sex and gender.

It is the adult world, though, that instils and nurtures prejudice.

The same hormone therapies that today are associated with helping trans people – the use of feminizing oestrogen for trans women and masculinizing testosterone for trans men – were used by endocrinologists in the middle decades of the twentieth century in attempts to ‘cure’ sexual inverts and intersex individuals, by administering hormones to ‘remedy’ the imbalance which caused their ‘disorder’. Homosexual females, for instance, would be treated with oestrogen. Homosexual males were sometimes treated with testosterone and, in some cases, with oestrogen in order to chemically castrate them and prevent them acting on their desires. In the 1950s such hormonal ‘cures’ for sexual and gender variance diminished (largely because they didn’t work), only to be replaced by psychiatric and aversion therapies – the underlying belief in sexual inversion and disorder remained. It must be stressed that the non-consensual, coercive and violent use of hormones to interfere with the bodily integrity of LGBTQ+ people and those born with intersex conditions destroyed countless lives and should be considered a stain on the history of Western medicine. This shared historical experience is also a point of unity for trans people and cisgender lesbians, gays and bisexuals, demonstrating our shared struggle against our pathologizing and mistreatment over the past century and more.
