I dipped in briefly - it's amazing that these medics constantly, explicitly and happily contradict themselves.
In one section HW and JOK are all about 'you have to listen to the child about what they want and when they want it' in terms of irreversible medical intervention. The children know best'. (ie, mastectomy, puberty blockers, cross-sex hormones).
But then later, when asked whether they treat 'non-binary' people (answer, yes, to help them in how they 'wear' their gender. Yes, testosterone to help you ''wear' you gender! Maybe we could all get a touch of prescibed coke to 'wear' our personalities a certain way?) they say that 'everyone's gender-fluid, even 'cis'gender people, it's always changing'.
Eh? Those two statements don't align. How can you take as given a child's determination that they are a different sex, medicate and perform surgery on them.
Only to say that 'we're all gender-fluid' throughout our lives?
Oh, and also the idelogical-bollocks and window-dressing that is 'the trans child's developmental pathway'. If this was a natural developmental pathway - it wouldn't need drugs and surgery, would it?
None of this stands up to rational investigation. No wonder #nodebate was in force for so long.
