Tell us how the existence of this woman with cancer means that men can literally physically become women.
Explain how her cancer logically means that her vagina is the same as one constructed for a transwoman.
One is a vagina, one is not, is the clue.
And I find your graphic descriptions there a bit much.
What you are saying is that there is No Such Thing as a vagina in the sense that it is a specific organ with specific functions that female humans pretty much always have.
You are saying it's the same as a hole cut in someone.
That is pretty offensive to women, can't you see that?
It is pretty offensive to this woman, to say that due to her cancer, there is no physcial differenece between her and a man who IDs as a woman and has had some surgery.
Women's bodies have always been no more than a set of holes and a couple of bouncy bits on the chest to men, anyway. So, suppose if a man says a surgical hole is the same as a woman's cunt, then so it must be.
