I think you are correct about trust being lost. I used to be one of the many women who didn't mind the idea of Dave A using women's spaces and for many years that accomodation existed with few problems. I accept that other women were less happy with the idea but still there were not enough problems to gain support to change things.
And then self ID crept in. Trans activists and campaigners such as Stonewall lied about the law and people thought self ID was the law and even when there were incidents which highlighted the safeguarding problems with self ID we were called transphobic for pointing them out.
When a violent convicted male sex offender raped two women in prison we were told he was one bad apple.
When another convicted male sex offender entered the female part of a spa in LA and exposed his semi erect penis in front of a 9 year old girl we were told you should teach kids not to look at other people's genitals.
When a New York drag queen who had participated in DQST was found to have been convicted of sexual offences against children and people said we perhaps needed to rethink the whole DQST we were accused of smearing all trans people. And who could forget dildo butt monkey - move along, nothing to see here you transphobic bigots.
And when we expressed concern about a man boasting about wandering around a womens refuge, naked, with an erection, and posting photos to prove it we were accused of trying to deny transwomen access to domestic violence services.
And we were still transphobic when a man took more than a dozen immigrant women to the British Columbia Human Rights Tribunal because they refused to wax his balls. The same man had quite a history of expressing interest in teaching young girls how to use tampons and posted pictures of himself in public toilets with a group of young girls, who were on a school trip, in the background.
And then women were being denied healthcare and access to support groups if they wanted women only spaces because the mighty penis was more important.
So I trusted and now I don't. No men, whatever they call themselves, in women's spaces ever. You had your chance and you blew it, that is not my problem.
