Originally a comment by Your Name’s not Bruce? on Certificates determine reality.

They have to work backward to the justification on the spot, which isn’t easy when there’s no valid argument that can get you there from sound premises.

Having failed to think very long or hard about trans “rights” when they took them on board means they’re having to defend claims that are impossible and extreme.

Humans have gender identities.

Humans can be “born in the wrong body.”

Gender identity over-rides sex.

In humans, sex is a spectrum.

Humans can change sex.

Each of these claims about the nature of material reality requires evidence and proof on its own, yet they’re usually sold together as a package, and discussed as if they were self-evidently true and necessarily connected. It’s not a single claim, but a whole mess of them, all of which are bullshit. Even if there were such things as “gender identities” none of the other claims would follow from that fact. There is nothing about the existence of putative “gender identity” that overturns the immutable, binary nature of human sexes. Even if being “born in the wrong body” was a thing, the brute fact of two, unchangeable and unchanging human sexes stands. Why wouldn’t it? Genderists still have all their work ahead of them. As an analogy, proving the existence of a god or gods would not prove the existence of Jesus. It could be that the gods are the Olympian or Hindu pantheons, or some other yet to be (or no longer) worshipped deity. Christians would still have to demonstrate the existence of their particular god before they could claim victory/hegemony/whatever.
