This thread really does make me despair. That in this day & age, on a site set up for women to support each other, that women can be so judgemental of the feelings/experiences of each other. Never mind completely dismissive of well reasoned arguments.
I'm shocked that the mother of a young daughter would be unconcerned (other than 'the conversation') at her sharing a changing space with 3 biological males. How exactly would that conversation go? Telling her some women have penises? Denouncing biology & feeding sexist stereotypes as the truth? Then what for lesson 2? The earth was created in 7 days & there's no such thing as dinosaurs?
Then what about when said 5yo is a 15yo who hasn't been taught that undressing in an enclosed space with 3 biological males (hell she won't even know what they are) is a potentially dangerous situation?
Attacks on women increased by 10% in England & Wales last year. Male violence isn't going anywhere, it isn't improving. Not that we'll have the ability to measure or define that in the future if things keep going this way.
So we'll be forced to pretend the problem has gone away. But we'll know it hasn't. But we've lost our ability to name the problem, the language to define it, the tools to fight it, to keep our daughters safe.
It's not just a toilet, it's incredibly naive & shortsighted to suggest it is. These things don't happen in a vacuum, laws are being changed, policies put in place, this is the start of a long road that we're all going down.
Women's rights are needed. They are important & should be protected so that our daughters don't have to keep fighting this fight. It's not unreasonable, it's essential.
Good luck to the OP, I don't fancy your chances much but I would want my complaint to be noted.
