However, subsequently, a mumsnetter said she had met her, and Jess told her to keep going.
Yes, that was me. I went to her book signing with a couple of other MNers (waves to @GinevraFanshawe and @venusinscorpio) & asked about the GRA, explaining that I'd been on the MN webchat and that a lot of us were worried.
Jess agreed that it wasn't that simple, that there were differences between women & transwomen & that we need single-sex spaces. She wrote "Keep fighting" in my copy of her book after.
