Ah, birth certificates. Finally something concrete.
So when you are talking about a "biological sex" (a property somehow known definitively only to the government), what you and the courts actually mean is what actual scientists refer to as one's "sex assigned at birth"?
Are you really claiming that "sex assigned at birth" is a scientific, rather than political-activist language? "Biological sex" is scientific, "sex assigned at birth" is a phrase purposely constructed to imply that there is something arbitrary about that assignment and that it lacks biological reality.
Both are real terms daily employed by scientists.
You'll forgive me if I don't quite follow your argument? We don't check CNN or Fox to tell us what we're allowed to call things today, terminology exists to facilitate conversation about a given area of study, not serve the needs of any particular party in any particular country. Certainly, your implied definition of sex assigned at birth is not correct. The sex assigned at birth is... the sex assigned to a child around the time of their birth. It is an extremely straightforward concept. Biological sex is not simple, and requires a bit more of a discussion to explain in full. Right-wing morons liek to claim that it is simple, and corresponds to their Bible somehow, but they usually get angry and start spluttering and contradicting themselves when specifics are asked for.
Sex is determined at fertilisation.
By what?
It’s commonly observed at the 12 week scan.
How so?
On what grounds?
With an accuracy of around 99.98%.
A. Bullshit made up number.
B. This is no less vague about how the determination is made, anyway.
C. And the legal question remains, if SDAB is incorrect in .02% of cases, how it would be just to use that determination as the sole guiding rubric for how formal legal discriminations should be executed. Even if it really
were only .02% of cases, that's still 11,500 British citizens denied the rights they ought to have, on the sole basis of incorrect documentation at the time of their birth. How is that justice for them, or healthy and safe for anyone else?
What has this to do with trans people?
You're asking
me what your stupid argument has to do with the issues at hand, now? I've been wondering that for a while, and only you can answer it. If you ask me, this ruling does
not and never did only affect "trans people", though I certainly take this statement of yours as confirmation that you know the purpose of these laws and the controversy is an anti-trans ideological movemnt, not any sort of science.
