If a man says that he is a woman, that is evidence you can literally become who you were always meant to be. That the defined power roles of gender are a buncha nonsense.

See, this continues to be the step that to me feels like everyone just accepted uncritically and I can't figure out why. Not only is it unfalsifiable it doesn't make any sense as a claim in and of itself.

How can someone possibly know if they feel like a woman or man? It presupposes that anyone, or everyone, knows what it feels like to be a gender. But gender isn't a thing that anyone can feel like.

You're baking multiple unfalsifiable claims into each other:
1. Gender has a feel.
2. People know what every gender feels like.
3. There is a correct gender for everyone.
4. People can identify which gender feels correct and perfectly so.
5. Whatever gender you feel like at any moment is correct. (Not sure on this one, reading the theory is unclear on this point.)

Nobody's ever demonstrated a single one of these to be true or even possibly true, let alone all of them. The amount of premises you have to grant is incredible. Perhaps the biggest one is that "social constructs" are not in fact constructed by society and imposed (if they are) from the outside but are entirely an individual identity based on personal emotions. When Tom Hanks was stranded on that island he constantly felt his gender.

If it's not questionable how anyone could believe this to begin with, they don't stop there, they go a whole additional step and conclude that this "feeling" is proof that their body has a medical disorder that has never been identified and requires them to pursue something literally impossible.

It's one thing for abject morons like Shreds and Kyuuji, but how could any field of any considerable reasoning take any of this remotely seriously? But then I remember my one of my own and how Marxism still holds such sway despite similarly being based on unfalsifiable premises for which no evidence exists.

At least with typical religions they have that whole centuries of cultural build-up thing, this is like people becoming Scientologists. They even try to remove their thetans for the same reason.

i am a car. i drove on the road, but got hit by another car. and they totalled me.
why did that car erase my identity?

Oh, look, the One Joke.

I don't know.  I definitely agree with the second part of your post, that people believe and go along with things in dogma.  But I do think "gender identity" has a "feel" insofar as people have a durable, consistent, internally felt self-classification.  I do think I feel like a man and not a woman - and I do think I can use my internal barometer to differentiate the two even though I've never experienced being a woman, just because I use some implicit reasoning to comport what I feel with the feeling of being a man because I have no dysphoria.   Because men and women are biologically different and have a distinct nature, I think there's some instinctual expression going on that I can infer is happening.  I don't believe I have to know "what it feels like to be a woman" in order to know that the label “man” fits me and woman does not.  I dont look down at my cock as a reference point, that sense is just there.  Like people who are right-handed people have never tried to live as left-handers, but they can still report from early childhood that writing with their right hand feels natural while writing with the left feels awkward.

 
I also think there are other mental states that we don't question.  Feeling confident, feeling homesick, etc....none of those are observable to other people and we don't dismiss them as meaningless simply because they are introspective.  And again, we use self-reporting in healthcare for reporting on the intensity of pain, anxiety, sexual orientation, etc.  
I will agree that like other self-knowledge it can be confused...and there is an unsettling coincidence of autism (and depression, and just general weirdness and not abiding by societal norms like getting a job) with transgenderism which makes me think there's a pathological link to a disorder and not simply something we should accept as normal and not treatable as a mental health problem.  Like its very doubtful that there isn't something else going on and everything about a trans-person is 100% normal aside from their identity.  Also, even if research eventually showed that trans brains match those of their identified gender, the idea of being “born in the wrong body” would still mean they are not actually men or women per their identified preference, because those labels inherently include the body as well.  I distinctly remember a dating site putting out data that shows 99.8% of heterosexual-identified men and 99.9% of heterosexual identified females do not want trans people included in their search results.  Numbers that high suggest that most people carry an innate, intuitive sense of what defines a man or a woman even if they or supreme court justices wont say it out loud, and that the transgender interpretation of those categories is artificial.
