Have you had a chance to read now Roses? Any thoughts?
My concern (i teach teenagers) is that I doubt, if you interviewed those 76 kids in 5/10/50 years' time, that you'd still find 76 people asserting that they were trans.
Now if school says 'OK Harriet, you want us to call you Harry & you want to wear trousers?' - that's absolutely fine & completely as it should be (& should be the case if Harriet just likes trousers!).
If school is encouraging Harriet to think she is, in fact, a boy; if they are facilitating her crushing her 13 year old breasts under a binder & sharing a room with her male bff on the school residential, that is not OK.
The best evidence we have is around 80% non gender conforming kids grow out of it. So that's around 60 of those kids who will not be identifying as trans as adults - before you even start considering the likelihood of a cluster of social contagion.
This is the concern a lot of people have. Do you think these concerns are reasonable?
