Just taking the opportunity to thank everyone for their many excellent and thoughtful posts, with a special mention to @prh47bridge for his expertise. I was interested in the debate over the WI and especially this:
In the WI case, since the only qualification for a man to join is that they are willing to say they identify as a woman, and WI don't ask any further questions or investigate to check that the person in question genuinely identifies as a woman, I think WI could argue that, as there is no actual requirement to be trans, any man can join therefore there is no discrimination
This rang a bell with me and, on checking the WI's own policy, the answer to the question 'Can male to female transgender people join a WI and attend WI events?' is:
Yes – anyone living as a woman is welcome to join the WI and take part in all WI activities. They should be treated in exactly the same way as all women who are part of your WI
But - Can crossdressers join the WI?
No – only those living as women can join the WI and take part in all WI activities
'Can men join the WI'?
No. The Women's Institute is based on the idea of bringing women together, providing them with educational opportunities and the chance to make a difference in their communities. Therefore, the WI is set up as an educational charity with a constitution which states that membership is only open to women
I’m pretty sure they’ve publicly doubled down on their stance when asked about eg Petra Wenham. Well, I know they have, because a sizeable petition from members was presented and they dismissed it out of hand.
(BTW I'm not a WI member, just driven to despair by the incoherent idiocy of all this)
