Possibly, though not definitely, my last thoughts on this:
I'm not annoyed that JM hasn't replied today or offered an opinion on this thread - happens all the time on MN. I thought it was reasonably laudable that she started the first thread, as she has had some criticism on here, and I was willing to see her in a different light.
However, what does annoy me is that she has said she doesn't feel like a woman, engaged in the whole gender/trans/cis dialogue and used those terms, told an eminent academic that she has no right to say who is and is not a woman, and then wilfully misrepresented that academic on Twitter on that basis.... And all of this without, it would seem, having one single opinion that she is able to explain or willing to share on what this thing 'woman' actually is. She has started this thread asking us to answer a question posed to her, and told us how we may debate it using an inflammatory term 'transphobic' - can you imagine a thread beginning: 'so, MNers, what is a black person in your opinion? And please don't derail my thread with any racism toward white people, thank you!'
At best it seems that Jack hasn't thought much of this through before making some very prominent and problematic statements about identity, and misrepresenting views of people who have thought it through. I hope she is thinking, reading, and researching to reach her own opinion about what a woman is. she has had plenty of help on here to be going on with.
