This is nothing to do with inclusive maternity services but to do with the idea that the words woman/girl/ and increasingly female must not be used ever when it's about our reproductive biology.
Women and is ok. I mean in the end not necessary imo but you know ok.
However.
To me the phrase birthing people. If I didn't know context and background. I would definitely take to mean those at the birth with the woman.
So I mean. That's silly.
The new language for women there is hardly any that is anywhere near as widely understood, and lots of it is very wooly and/ circular.
Eg people with a cervix.
If never had smear or baby. Plenty women don't know if they have a cervix personally. They ASSUME they do IF they know cervix = woman. Because they know they are a woman and so can expect to have one.
No one thinks person with a cervix full stop and no further steps to parse it.
It goes person with a cervix = girl woman female. Therefore it means girl/ woman / female.
An extra step of translation which not all will know, and in the end the answer is still because woman female girl.
It's a euphemism as so many things about our reproductive organs and processes have always had. Because unmentionable.
Now the organs and processes must be front and centre because woman/ girl/ female are unmentionable in relation to them.
The link is not altered at all. It's just not to be drawn attention to if you're a decent person.
It's all shit.
