@Gnomeshatecheese @LostInCalifornia I think it's mainly too vague.

If you handle definitions of self, everything about you and all you may do plays some kind of a role.

Thus, it's trivially true that there is more to a woman than to bear children. So that part is not making any interesting distinction. People see women after their menopause as women too, so big whoop.

Now, the biology argument runs a bit short, with respect to the many aspects. One may feel as a woman for oneself, even without the biological aspects - because feelings don't need to come from logic. I could feel as a bear, and no matter how strange others might find this, it would still be my feeling, if i had it.
Where it gets complicated is when people interact more than casually. I could wish to be called bear as a greeting, but asking them to let me shit in their yard would be taking it too far.

So, in conclusion: My feelings are mine, and some respect for them is warranted as a basis for our society to work. But when someone is affected directly, it is about them as much as it is about me, and my self definition is not enough to define what is and is not ok. Even the biology is not defining, as others might refuse something that affects them due to other aspects of me.

So all i have to say about the cited post is: too vague to say anything interesting. Just ragebait, no philosophical statement is present.
