Personally as we have just escaped a sort of tyranny of allowing a small group to demand across the board social impositions I take a dim view of replacing it with another tyranny of not allowing voluntary groups such as the WI to decide for themselves.
They can decide for themselves to allow TW to be members - the ruling won't stop that. What they can't do is call themselves the Women's Institute and pretend that the male members are women. If it goes to a vote and the members are happy to include TW, and if it is made clear to members and potential members that this is the case, I don't think there is any reason why they can't. I don't see it as tyranny, just being truthful.
The problem is that calling it the Women's Institute, which clearly states it is not open to men, allowing TW in is akin to saying that they are women, which contravenes the ruling. It's unfortunate for the people who might have to leave, but the law has to apply to all. We found ourselves in this position because we allowed the 'creep' of cases that seemed reasonable, and they mounted up.
I understand that it seems cruel to 'genuine' TW, but this is a direct result of the behaviour of the TRAs and 'allies'. If the members feel that it is ok to allow people who 'identify' as women to join, then unless I am misunderstanding the guidance, that can go ahead. They can't just impose that on the membership though, which seems reasonable to me.
