We're all lacking facilities. Public facilities are being closed and cut left and right, people are fighting for better, but that doesn't explain how trans and other dysphoric people are the step too far in trying to make do with what we have now rather than arguing that there is a desperate need for more facilities. Most trans and other dysphoric people aren't the ones trying to take away our rights as disabled people, it's the ones who actually have the ability to do something about the shite situation we're in.
Many people dislike the space-saver arrangement of putting the baby changing facilities in disabled loos, but I've yet to see anyone claim that parents or the staff that points them to towards those facilities as they've been doing for many years now are somehow taking away our rights as disabled women we know it isn't the staff or the parents' fault that this is the way it is yet I regularly see trans and other dysphoric people blamed and told we need to do something about this situation as if we're somehow in control. Those in charge like to appear 'right on', but will do the laziest option possible no matter what solution we put forward - that's how it's been for years. We all know this, so why it is when it comes to trans and other dysphoric people, we're a step too far and need to be asking for things many of us have been asking for for years?
This isn't new. I was first told my dysphoria meant I should use disabled facilities about twenty years ago. This has been the way to deal with it long before I was around which is why people have been fighting for changes. I'm disabled, dysphoric, and still female - I'm not trying to take away dude's rights to a changing room either or disabled men's rights, or however people would phrase it when it's not a trans woman doing it.
We've been asking for unisex single stall spaces for years. The ones throwing people under the bus as those in charge, with the money and power, who find this lazy solution suits them, general people and staff who are used to this solution aren't really to blame nor are trans and other dysphoric people, not anymore than parents are to blame for changing rooms being put in disabled facilities.
