Well this is a right mess, innit?
If the FM don't really believe TWAW, why should we?
The hypocrisy by the FM is fairly evident, considering they do have female chapters, the 'solution' could have been that TW once the don the frock, shove them into Pink Ghetto Lodges.
So is this move more about 'we are losing so many members that want to get their frock on, what can we do?'. Because that is how it reads.
As usual though, it is a bit coy on the 'surgery' part, given most trans of either sex don't actually have the genital surgery. Sure, the more committed 'transmen' have the double mastectomy, so could pass the breast-baring part of the programme, but a number (not all) of TW would not for the same reason. The whole point of the breast baring is to prove you are not a female in drag.
I doubt that there would be many TM invited to become members, given the invitation system.
