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.
