It's not bias. The presence of autism in children referred to GIDS is significantly higher than in the general population. You have to wonder why autistic, gender non conforming, and gay kids are so massively overrepresented at gender clinics and ask whether these children are simply suffering from distress about their sex that would be a passing phase if it wasn't medicalised and affirmed.
We need to know more or this is not meaningful data.
A diagnosis of autism does not of itself lead to a conclusion of lower functioning. Aspergers Syndrome is often indicated by higher functioning individuals.
I worked in a special school at one time for a number of years. The school conducted specialist services in-house - being a private school.
The school was a specialist school for those with dyslexia with an international reputation for outstanding results. Here's the thing, many of our learners were referred due to difficulties with reading and writing, too often the UK (and some other states) proved to be reluctant to intervene due to funding issues. The school's testing regimes frequently found conditions comorbid with the learners' dyslexia, quite frequently some traits of autism that were previously undiagnosed. Therefore the school would appear to have rising rates of autism among its learners, which on one inspection caused one inspector to assume that autism was some kind of contagion within the school. Thankfully the school managers were able to straighten out this inspector before the report was published.
Whether children and young people are considered for medical purposes is not based on what diagnosis for certain conditions are, but by their Gillick competence. It is perfectly possible to have a cohort consisting 100% of young people said to be 'on the autism spectrum' and for everyone of them to over the age of thirteen and be Gillick competent and therefore meet the legal requirement for them to have control of their healthcare.
So you see, I'm not going to buy into this scare narrative that a high incidence of young people with autism makes all of that number vulnerable to interventionism. It doesn't.
At the same school there was a young learner. She had diagnoses for dyslexia, autism, and defiant oppositional disorder. She also had a heart condition meaning that the school had to ensure that she did not participate in activities that would lead to a heart rate above a given level. She wore a monitor.
When she reached her thirteenth birthday, she asked to be tested for Gillick competence. She came out as fifteen. She removed her monitor and removed herself from the waiting list for heart surgery. Despite the many protests she continued in school on that basis. Today, fifteen years later, she and I are fb friends. She qualified as a nurse, and is now married with two healthy children (twin girls).
On the other hand I know one person, not from the same setting, who had also had comorbid conditions including autism. She had been taken into care, her father was later placed on the sex offenders register. My own judgement from her complex pattern of behaviours was that she was not emotionally stable to complete transition without more support. She used a NHS GIC and completed transition in a number of years. Neither the GIC or the final assessment panel picked up on her conditions or concealed emotional state. Despite my own concerns she has not detransitioned, not offended, but has made some serious errors of judgement.
The GICs, like the TC are seriously under-resourced and under performing.
You and I may share some concerns, but we part company in how those concerns are managed.
