Of course I don't support punching people including trans exclusionary people.
Pratchet
Supermatch your argument is empty and ridiculous.
No it's quite well reasoned and factual.
Neither allies nor consensus have any bearing on what is true, and what is not true.
Sorry consensus? There was a consensus that the earth was flat once. There is a consensus now that it's round. There is a consensus on climate change. There was a consensus in parliament when the GRA was voted through.
It is true that no one can change sex.
You can change sex legally - that is factually correct.
"Where a full gender recognition certificate is issued to a person, the person’s gender becomes for all purposes the acquired gender (so that, if the acquired gender is the male gender, the person’s sex becomes that of a manand, if it is the female gender, the person’s sex becomes that of a woman)."
You can change sex hormonally. You can change the body to resemble the acquired sex as much as currently possible by medical science. It's adequate enough to relieve gender dysphoria for many. You can't change someone's chromosomal sex. No one is saying you can.
It is true that innate 'sexed' identity has never been detected.
Where is the evidence that there is no biological component to gender identity? Show us the evidence?
There is some evidence that there is a strong biological/ genetic component. www.scientificamerican.com/article/is-there-something-unique-about-the-transgender-brain/
Overall the weight of these studies and others points strongly toward a biological basis for gender dysphoria.

It is true sex is binary and defined by reproductive role.
It's one definition. It is not the current legal definition. You can be legally male and not have a male reproductive role.
These things are true whether the American Christian Right, or you, or I, or anybody, or nobody, believes them or disbelieves them.
Nothing you have said is actually true. But you only seem to believe things to be true if you think they are true. But why let the evidence get in the way of a good story?
