I think it all hinges on the legitimacy of the concept of gender identity.
Psychiatrists aren’t infallible no, but don’t you think if they had an alternative evidence based cost effective treatment they’d be using it?
From bbc etc earlier in the year:
In the previous version - ICD-10 - this was considered a gender identity disorder, in the chapter entitled mental and behavioural disorders.
Dr Lale Say, a reproductive health expert at the World Health Organization, said: "It was taken out from mental health disorders because we had a better understanding that this was not actually a mental health condition, and leaving it there was causing stigma.
"So in order to reduce the stigma, while also ensuring access to necessary health interventions, this was placed in a different chapter."
Commenting on the revisions, Graeme Reid, lesbian, gay, bisexual, and transgender rights director at campaign group Human Rights Watch, said the changes would have a "liberating effect on transgender people worldwide".
