Your information is a good five or ten years out of date, statsgeek1. The majority of children now presenting to GIDS did not experience distress for a long time, the new and entirely atypical* cohort of children presents as post-adolescents across the entire Western world.
And we wouldn't have a court case against the Tavistock alleging malpractice (including insufficient psychological support) and asking for the experimental treatment with puberty blockers and cross-sex-hormones on underage children to be stopped and we wouldn't have countless medical professionals, including a professor of evidence-based medicine stating that informed consent is not possible if what you say were true.
And no, the UK is not known for a conservative approach to gender dysphoria. As the UK has adopted a Memorandum of Understanding that holds that counselling which seeks to explore the underlying reasons for a diagnosis of gender dysphoria and to reconcile the sufferer with their body is conversion therapy, the UK unlike most countries in the world is following an affirmation model.
Having abandoned the successful Watchful Waiting approach, which seeks to minimise iatrogenic harm by delaying any medical transition, we are now in a place where children are affirmed and socially transitioned long before a diagnosis, and referred for medical transition without adequate psychological counselling.
As this is of course incredibly harmful to children, 35 psychologists have resigned from the children's service in the last three years because the affirmation model means they cannot do their jobs properly and they cannot protect their patients. That's an unusually high staff turnover, even for a high pressure environment like GIDS.
I am honestly surprised you are unaware of these developments.
*atypical in that 50+ years of research and empirical data into the condition have not only suggested a much lower prevalence rate than what is currently happening (6 in 100,000) but also atypical in the timing and manner of their first presentation.
