Seems like you put way too much effort in opposing such a simple change. Why care at all if its changed to "people"? You sound a lot like people "just asking questions."
"Biological female" is also a big red-flag.
Some FTM may not even come out until they're already pregnant. Some may choose to not take HRT for the purpose of having a biological child. And you don't need to take HRT to be trans, so it also sound a bit too transmedicalist.
