That's a brilliant and deeply troubling article. Reading it I suddenly had the insight that transitioning could actually be a really understandable response to being a teenage girl today. There are so many horribly gendered stereotypes forced on them, and so much confusion in the messages they get about sex, that I don't blame them for trying to opt out.
Further, in this capitalist society everyone is encouraged to imagine that they are wrong if they don't fit in with the barbie-doll image of womanhood they are presented with. There's no sense of trying to change the world, just of trying to change yourself. And yet, as the heartbreaking stories above make clear, we all want to feel part of our peer group and be accepted for who we are. So these poor girls feel they have to transition in the hope of finally fitting in.
I'm a lesbian and have never doubted that I am a woman. However, if I was a teenager now I can quite easily see myself being tempted to go down the transition route, and that terrifies me.
