Keira Bell is in the front line of those resisting this, a woman who took testosterone while she identified as a boy in her teens, later felt this was the wrong decision, and writes about the lifetime medical impact and changes to her body as a result. She particularly talks about the adults who enabled where she feels strongly they should have protected her.
How many Keiras in that 200+ who will live with lifetime damage and regret? How many are 'dismissable' as a regrettable side effect of making the other children happier?
What, if as posited, it does turn out that missing pubertal development does call permanent changes and detriment to brain development?
What, just wondering, might be the potential dating pool for young adults incapable of sexual arousal and with prepubertal bodies who are physically legal but cognitively permanently stuck in childhood? Rule 1 of safeguarding: think the unthinkable and ask the difficult questions.
At one point lobotomies and electroshock therapy were all the rage. Should a child be able to have one because they want one and their parents agree?
And as many have noted: the supreme court judgment about restoring women's existing legal rights is so terribly 'complex', needing all sorts of assessment and consideration and discussion and votes and kicking into the long grass for years because it's just so hard, but this? Slipped quietly through and it's fine.
I would be certain that these children and their families will be tightly locked into legal contracts that ensure they have no come back should it turn out their lives were destroyed in the process of this experiment.
