We are going to be fighting this push for a long time. We know.
For the sake of supporting your own thoughts on this, can you tell us at what point exactly does any male person become a female in your view as being suitable for inclusion? Do they have to cruelly have their penis removed and live with the unhealing wound in their groin for the rest of their life? Or is it a name change?
Who arbitrates who has become sufficiently 'female'?
Do you begin to see the issue? It is not even a kindness to say that some male people can enter these spaces and some can not. It cruelly puts those people that others consider vulnerable into a position of having to make themselves medical patients forever. All to allow someone to be kind.
And another question, if a male person doesn't want to be bundled in with perverts and offenders, wouldn't they respect female people's boundaries and just find alternative solutions for themselves? We are told by many male and female trans people that they are doing this anyway. The male people who seem to understand and respect female people's needs don't trangress into female single sex spaces. We have been told about how many of them have realised and have stopped coming in.
So, are you even talking about the same group?
I am pointing out issues that maybe you have not considered in the hope that it might start making sense as to why women, who have thought about this deeply and discussed it thoroughly, have the position that they have.
