There was a Q&A session, and much to my horror surprise I was picked to ask a question. I asked her whether she felt it was important to make the distinction between biological sex and gender identity when discussing women's rights (she's co-founder of the Women's Equality Party, who have previously said TWAW).
She said it was an important issue to discuss (rather than #NoDebate) and the way rights intersect and overlap is something that needs discussion.
Ok, it's not a ringing endorsement of the GC position, but it at least indicates a willingness to discuss the issue, and acknowledges that there IS and issue, which I think is progress.
I'm planning to write to her to ask for a meeting to discuss this - watch this space.
