That's a sensible commentary, slugs.
As soon as I first saw this idea raised (it bobs up occasionally, like an unflushable poo), I thought of the fact that emotional trauma produces many symptoms that look a bit ASD-like. I know this because I have a form of PTSD, have had over 10 years' treatment, and have explored this very thing in depth with my therapists. I officially don't have an ASD or a personality disorder, both of which I'd self-diagnosed on a reasonable basis.
We're not likely to overlook the emotionally traumatic nature of gender dysphoria. We're always being told about it. This will produce symptoms of extreme self-consciousness, social glitches and behavioural dysregulation. Unfortunately there's a large cohort of professionals with a transgender agenda (heh, say that out loud!); the more sympathetically they can pathologise GD, the more authority they accrue and more confused, vulnerable young people will be sent their way for transformation. As your source points out their studies are woolly, biased and uncontrolled. Nothing much to see here. Unless you're an emotionally fragile young person with a poorly-diagnosed ASD, in which case you may be at some risk of having your identity reshaped.
