It’s just that men are allowed in women’s spaces now. If the man says he is a woman - a ‘trans woman’. So we have no spaces for biological women only.
AS said earlier this is a myth.
Wherer "proportionate" it is legal to have single sex (biological) spaces, services. etc..
It isn't that this cant be implement but many just cant be bothered, and worse still, too many women dont want to be "unkind" and so dont pressurise providers to provide women only.
The problem isn't the law, but so many people have been Stonewalled. It is these fellow travellors who are taking away women's rights.
Not to recognise this is to not to be able to campaign against it.
Its not just men imposing themselves on women, it is that too many women now think they should accommodate those who identify as men.
And as said so often, no other protected characteristic group would tolerate including someone who says they "indentify" as "Black" or "disabled" etc..
And unfortunately it seems they aren't impressed by those of us who are challenging this.
