SarahCarer - some more thoughts below. Apologies if this is too long and I might have wandered into some confusion at one point.
your understanding of gender identity as produced by a range of factors with specific emphasis on biology
I don't think I'd say my emphasis is on biology, just that genetics and biology are evidenced components. As others have said identity development is multifactorial. Whatever its antecedents, gender identity appears to be immutable - in most children and adults (not all).
the idea that the crossover of ASD and GID and homosexuality and GID is EVIDENCE of the social nature of gender?
Ok but I'm not understanding your thinking. ASD is neurodevelopmental. Homosexuality likely has a significant biological and or genetic cause. So if there is an intersection with GID does that not indicate an even stronger likelyhood of a biological element in GID as well? Otherwise why would they coincide? Yes there could be a social cause but 2 of the 3 already have an established biological element. So yes it could point to a social cause, but at the very least (and possibly more so) it could also point to a biological cause?
The rigidity of thinking is some ASD people could contribute to the confusion in establishing gender identity in some individuals where there is already gnc behaviour. Or it could be that there is some sort of underlying developmental/ biological cause underpinning both, in some cases. There could be as many different combinations of factors as there are people.
For me a more social one would be say: a child who suddenly their school work declined, they avoided social situations, had suicidal ideation. 3 things. The common underlying cause could be 'bullying' as social cause. Reading that back I don't know if that helps really I'm just exploring the ideas. (I wasn't sue whether to delete this paragraph!)
If I was a referrer and I concluded that GID in children was actually a response to mass societal homophobia and gender based oppression and never referred children to a GID clinic but instead went down a CBT route with family and school interventions to address the stories and narratives around gender and sexuality that were harming the child, do you think I would get away with that?
Why would you conclude that it was a response to mass societal homophobia and oppression? When there is some evidence of biological element to both sexual orientation and gender identity? Also hasn't conversion/ reparative therapy failed for both homosexuality and GID?
Why would it be ok to try CBT for GID but not sexual orientation? A valid answer could be because GID requires medication and surgery and it would be best to avoid that. I agree. It would be best if anyone could avoid medication and surgery. Ken Zucker has tried that with children though. I actually supported his work. I don't think he was transphobic or homophobic. But I find it odd that in the whole world only one single person was openly trying it. That actually astonishes me... that in recent times there is only a record of one person openly trying to discourage a transgender outcome in children - in the entire world? That must tell us something surely?
The current thinking appears to have moved on to say that transgender identity is not a disorder - but a normal variant of human gender/ sex/ identity (whatever). I'm not sure I agree with that because I think if you need medication and surgery to function properly then surely that is a medical condition? What else is it? I guess they have dealt with that by changing the term to gender dysphoria.
"none of us can fully understand it" "a lot more research is needed" and then they go ahead and treat with chemicals and surgery, giving the patient the benefit of the doubt that this indefinable thing that we don't really understand is best accepted and reinforced even if there is a completely separate underlying cause.
So it comes down to what do we do with someone that is in extreme distress and we don't have an evidence base to 'cure' it? But there is a small amount of evidence that the chemicals and surgery route does have a positive outcome for some. So what do we do?
