For trans people, it’s more complicated. They still need a political movement. There’s an opportunity to reframe it around clearly defined objectives and a will to resolve conflicts with other groups rather than simply to steamroller them. They might take the lessons of the women’s movement about building and running services that work for them, rather than trying to hijack institutions developed by women for women. Most of all, I hope they walk away from the absolutist ideology of gender identity and accept that “being trans” has an extraordinary range of causes: from traumatised female adolescents trying to control their bodies, to effeminate young boys whose parents think playing with dolls is pathologically girly, to those like Caitlyn Jenner who cheerfully concede that dressing femininely has an erotic kick (“dressing up like this is the equivalent of having sex with myself, male and female at the same time”).
