If it was, there would be the simple matter of a brain scan to diagnose it. But, of course, there isn't, because all the studies activists like to quote do not control for, as one example of many, homosexuality. If it was possible to diagnose dysphoria via a brain scan, it would be protocol. It isn't, so it isn't
That's just not true. New diagnostic techniques are developed all the time. Just because it isn't possible now, doesn't mean that there are no biological differences that may be used for diagnosis in the future.
And even if it were possible, it wouldn't mean that someone has a soul, separate from their body, that belongs to the opposite sex. It would just mean that their brain, be it male or female, was slightly off kilter to the population average for male or female brains. Just as a 6ft 4in woman is an unusually tall woman but not a man.
I think I agree with most of this. I'm certainly not arguing for souls or that transwoman = woman. I'm arguing that there may be a biological basis for the feeling of gender dysphoria and that there is evidence that supports it, but no proof as yet.
