How is stomping your feet and saying NO going for you?
Slightly better than when we were accepting pronouns and being kind and agreeing TWAW because we thought they meant we should accept TW as if they were women socially, not that womanhood itself is a collection of mental traits found in either sex and therefore male people's experience of womanhood has no less authority than female people's. We didn't think saying TWAW to support vulnerable trans women being left alone to live their lives would turn into male bodied people in women's sport, or prisons, or taking women's officerships, or male rapists and sex offenders, crimes that are common in males and rare in females, being accepted as women, because that's not reasonable and most people are reasonable and know sex matters.
And yet, here we are. All those things are happening and anyone saying publicly this is not fair on female people is dismissed as a bigot because trans women ARE women, and if it turns out some women have the type of body that is better at sports or more likely to be physically or sexually violent or comes with 30 years of male privilege well so what? You are all women together and you should celebrate the achievements of the people who took them from you.
So now we say NO because every time we said "Yes, but...." they just took the Yes and gave us No Debate.
The only difference between us and you is we already tried the things you think will work and know they didn't.
You should look at the Hansard record from when the GRA was being debated. See things that were dismissed as fear-mongering and never-going-to-happen at the time are now framed as totally valid and transphobic to question.
You keep saying we should not base our arguments on the TRAs and that most trans people and their allies share many of our concerns. So why is it that TRAs are being left to do the lobbying and set the political and commercial agenda? Why are these moderate trans and trans-ally voices, the ones you say agree with us on many things, not speaking up? They are assuming rational voices will prevail but not taking the risk of being those rational voices. They leave it to us so they can denounce us and stay safe even when we say what they also think in private.
You say you don't want this debate to be a polarised screaming match between what you see as two equally bad sides, but your solution seems to be try to move one of the sides nearer the centre and hope the other takes the hint when it needs to be for the people already in the centre to find their voices and bloody well speak up!
(and let's be honest, we all know the reason you are trying to move us and not the TRA side us because it's safer to disagree with us than them)
