You seem to have done a lot of reading. Do you have a scientific background? Is your stance based more on how you perceive yourself and your identity?

Yes, yes, no.

"I am missing something."

Two points, I think. The first is that there are very very few people who are actually "anti-trans" in the sense that they believe in legal discrimination against trans people, outside of the specific and well articulated "sex matters" issues. And the establishment of neurological evidence doesn't move the needle on any of those issues.

The second is that for in general, you're trying to establish a scientific/rational basis to convince an irrational society who mostly comes to its conclusions on these matters outside the realm of scientific reason. Emotions, religion, etc. They don't care about neurological evidence either.

That's my point, bascially. Again, I doubt if brainscans will ever be able to point to one specific characteristic enabling scientists to say "There it is -- that's the neuromarker for transgenderism, right there."

But, even if they do, the vast majority of people won't care, because it doesn't affect their opinion on the matter.
