That’s fine then.
Transmen can be birthing people. I would happily refer to a transman as a birthing person.
As long as if that’s agreed for transmen, then females who want to can be called mothers, or pregnant women, and have the right to be called that including in maternity wards and on forms and at appointments instead of having to accept what trans want.
Actually the perceived ideology on this forum isn’t men are doing it all-except perhaps in your mind.
“There are women who choose to be transmen or even non binary and no man is telling them what they must be.”
Again, you miss the point of the discussion-deliberately or because you simply don’t understand.
The point is that some men-claiming to be women are eroding women’s rights, telling women what they are entitled to, or how they should feel, falsely applying for a job that was specified as for a woman, claiming to be women because they can’t succeed as men.
I agree with what was posted earlier, that we should use female or male, transman or transwoman. I wonder what MW would have put on the form.
