I'm all for inclusivity, but there's a certain point/form of language policing where you're asking folks to perform a lot of mental labor to adjust their language to reflect an extremely rare edge case. Like why?
It's like if we insisted that people avoid the phrase "look at this" in general communication lest you offend/exclude a blind person who might be listening.
I've never heard 1 democrat politician say "birthing person".
This was never something "democrats" said and always something that rightwing media says that Democrats say.
There's nothing to drop or defend as this is completely a distraction from real issues.
Basically, rightwing media LOVES picking fringe individuals pushing a position and pretending like every democrat actually believes the same.
These word changes were real things that happened by government policy.
Literally the first sentence in the guidelines that talk about birthing person.
The entire paragraph says "it's fine if you want to" and isn't prescriptive.
This is a fake controversy. You are literally just mad that some people recognize and want to be accommodating to trans people.
I can't even humor your assumption that there are only two sexes and one birthing sex, because intersexed people exist, as do people with unusual chromosomes. Some of them have wombs and can give birth. Language like "birthing persons", while awkward, admits the existence of those people into a larger group without requiring even more awkward phrasing akin to "women, and men with wombs, and intersexed people with wombs".
My point is, our interpretation of these observable biological processes and facts, and our response to them, is socially constructed. There are many Doctors and Scientists who do very much agree with this complex view, just as I'm sure there are those who believe in a strong binary like you. I see the complex view here as much more useful, especially in navigating things like human dynamics and healthcare needs in ways that benefit us all

tl;dr: All boy moms will have some proportion of XY cells lodged in their bodies until they die. And this can result in them showing up as genetically male on a DNA test, simply because they once gave birth to a boy. When you get down to a cellular or molecular level, notions of "sex" or even "individuality" are far more blurry than our mental models admit. Sorta like recent findings that by cell count, humans are only about 43% human, and the rest is the bacteria making up our microbiome, and that our microbiome can have significant impact on our behavior.
The term that Hispanic queer and non-binary communities use is latine, which is pronounceable, follows normal Spanish grammatical rules, actually arose from the communities being discussed, and pluralizes easily to "les latines".
There is no person that can give birth and is not female.
Only about 4% of the US Hispanic population uses it, 75% say it should not be used, and half have never even heard of the word. It doesn't fit Spanish grammar or pronunciation rules which makes it look even out of place.
Latinx is attempting to provide an umbrella term for latino and latina, it's not renaming one of the two.
"Birthing person" is attempting to provide an umbrella term for people who can give birth that may or may not necessarily be female. (You can express your own feelings about the reality that this exists, but it does exist regardless of how you feel about it).
On the other hand Lake Ontario is a real lake that already had a name and now someone is trying to give it a new one.
