I've post this on another thread but I would so much like to hear when the question "what is a woman?" asked that the response is "that's the wrong question, a woman is indisputably an adult human female. The question we should be asking is what is a trans woman and when does a man become a trans woman?".
The reason is that as soon as you engage with the question of "what is a woman?" there is the sub text that it is a matter of opinion and any answer is naturally defensive and "on the back foot".
As soon as the question is reversed we start to get to the core of this debate - that a man doesn't need to transition in any meaningful way. They don't need to take hormones, have surgery or uphold outdated and regressive sex stereotypes on how they present (dresses/make up/long hair/heels). The "become" a trans woman at the point they say they are.
This is who women are being expected to give up their sex based rights for.
Men who observe our sex when choosing the spaces that fit their "requirements" yet expect women to respect their gender in those spaces, whilst claiming not doing so is bigotry - oh the irony....
