I think the reason I don't currently care - and that hasn't always been the case - is that the trans community isn't trying to find a compromise.
At the moment we have women expending huge amounts of emotional labour both defending our own reasons for wanting single sex spaces, sports, and even the vocabulary to describe ourselves as a sex class, and proposing potential solutions which would ensure respect for women's safety, dignity and equality, and also for trans people's. And what are trans activists doing? Rejecting it all out of hand.
Third spaces don't exist.
Then let's campaign for, fund and build them.
That will never happen.
Let's try.
It would take a long time and trans people have needs now.
Let's start now. Where there's a will, there's a way.
Even if those spaces did exist, it would force trans people to out themselves.
Your allies can use gender neutral spaces with you out of solidarity.
Why should we be forced into a third space? That's othering.
But you are "other". You are the opposite sex.
That's transphobic.
And on and on it goes.
The sad truth is that trans activists are not currently looking for any solution other than women just shutting up and giving them what they want.
It's not enough for trans people to safe spaces to pee and get changed in dignity. Those spaces must also have members of the opposite sex in them in order to validate their belief that they are the same, that they fit in. The feelings of those other people are irrelevant, they don't matter.
Many trans activists have openly said that even if third spaces did exist, they would not use them but would continue to use spaces for the opposite sex. So not only would it involve spending a huge amount of other people's money that we cannot really afford in order to create these spaces, it may well be wasted money unless it were accompanied by draconian new laws making it a criminal offence to use spaces for the opposite sex where a unisex space is also available.
I have now reached the point where I am unwilling to expend any more time or emotional energy trying to find a solution to a problem that they created and have no interest in resolving. Unfortunately I think the only way to force a sensible, productive discussion about how to protect the safety and dignity of genuine trans people is for women to rise up, en masse, and say, "Trans women are men and we do not want them in our single sex spaces and sports. We refuse. The answer is no. The answer will always be no. Now find another solution. We did not create this problem and it is not our problem to fix."
