The sex/gender difference wasn't established.
The question was significance of being a woman, the term woman usually referring to an adult human with a vagina, genetically XX, and who espouses a feminine gender.
Now, if we broke it down into what's meaning of being a member of the feminine gender, we might get different answers, but that wasn't how it was worded.
But I do see your point, Orangey. Maybe we have some trans members on this forum?
