I may be coming at this from a different angle but I don’t want to take away rights from transgender people but I think that women need spaces and self I’d is open to abuse.
My argument against self I’d is it is not a proportionate response. There are a tiny number of transgender people are they are outnumbered by abusive men.
The concept of self I’d was first used by disabled people. Not one person is now arguing for self ID for us. We are excluded from many public spaces due to them not being accessible. It would make my life easier if I could self ID and get PIP and a blue badge. I understand why they can’t do that because if that was possible everyone would do it. If you are giving people rights there needs to be safeguardeds in place.
I thought this was a different way of putting it. It is irrelevant where or not you think trans women are women when the biggest worry is people who don’t identify as women saying they do.
