'Gender identity is just one of thousands of sex characteristics. When allocating sex, GC people sometimes prioritise gametes, sometimes gonads, sometimes chromosomes, sometimes socialisation - kind of depends which one you ask, and when you ask them, but trans inclusive people tend to prioritise gender identity.'
Just to post that comment again.
It's fascinating really.
The thread is about newborns.
'GC' people don't have control of the global birth records 
I mean unless you mean the 99.99999% of the world population who knows what boy and girl means and when they say it about a new baby they're referring to sex... But it can't be that as were told frequently that most people are totally onboard with self ID etc
The fact that through human history everywhere it's been bleeding obvious the vast vast majority of the time what sex a baby was from a quick glance is... Not of consequence? Or, not and never was universal? To look at a baby and even from the beginning of humanity know if it was a boy or a girl?
This is now supposed to be an outlying and bigoted position?
That's pretty bold. All humans for thousands upon thousands of years have been sending babies incorrectly?
