So why are you doing it — you are the ones that are campaigning to get transwomen excluded from spaces that they are perfectly entitled to use at the moment!
I'm campaigning f to ensure that protections in place for women are upheld. Im campaigning to ensure that predatory males are not able to get even easier access to women. The focus, hard as this might be to believe, is not trans people.(Believe it or not, not EVERYTHING is about trans people) A by product of ensuring safe spaces for women remain, would be to have stricter procedures for those who were born male. Yes, I have no problem admitting that my first priority is women who were born female.
A significant part of me is very uncomfortable by the added layer to this that some trans people rifle through toilet bins for used tampons, that go to smear tests to see if the nurse thinks their surgical vagina is 'real', that chats on Internet forums about how they went in changing rooms and 'passed'.
You might also want to target the 'figureheads' of your campaigns. The ones that present hyper-sexualised images of themselves and think that being a women is all about dresses and hair and make up. Their desperation for validation is palpable.
If there had been one jot of consideration for the needs and fears of women by your 'community' then we must be able to actually have a discussion. But everything is dismissed and trivialised to suit your agenda time and time again so no, no negotiation.
