I agree with Kirk
Yes there has been regulatory capture of so many key organisations so fast and so deeply which is so dangerous, but lots of women are challenging specific instances of this through democratic and grassroots means all the time. Big or small actions, through talking to family, friends and colleagues or through high profile legal cases.
It always pops up again quickly somewhere else but we always knew this is going to be a very very long game.
The key thing to hold on to is what Kirk said, the vast majority of people don’t support this. As soon as they realise what this dogma means for themselves and their families and friends they are very shocked. Most people want there to be reasonable provision to support the rights of all!groups, which is not served by one group steamrollering over another.
The starting place to move forward on this is for everyone to acknowledge that the literal ‘TWAW’ belief (which enables people to believe that transwomen can be lesbians, to put men in women’s prisons, hospitals and sports fields etc), constitutes a serious clash of rights for lesbians and women of all ages as a class and for female and male children (since they are often in the care of women).
Until this clash of rights is acknowledged and objectively examined then clearly this issue can’t be resolved. So it is a major contribution for us all just to point out this clash of rights to other people when we see it and feel safe to do so.
So TLDR; women have not lost this, Yeah* although I absolutely understand how it can seem overwhelming or scary at times.
Look after yourself and try to keep on talking to other people IRL who get it.
