It's not 'woman' because they include males in that.
It's not 'biological woman' or 'adult human female' for the same reason.
It's not 'cis woman' because that excludes women who don't identify as women.
It's not 'afab' because, first, that's an adjective not a noun, and second, it means 'assigned female' - so technically, a male person could be assigned female at birth.
That leaves no word at all for biological woman. Isn't that a big problem? TRAs and TRA supporters - can you answer this one?
