I have been reading this thread and other threads with interest. I am very new to this debate, but not these issues. I grew up in a very left wing, very inclusive environment and supported people's rights to self determine their gender.
I have now looked at the evidence and data that has kindly been provided in this and many other threads, and I have changed my mind. I now support women only spaces. Biological women. I realise that women's (and especially lesbians') rights are under threat. The refusal of people such as Rose and Early to engage and answer questions has also greatly contributed to this change of heart.
Moreover, as someone with a past in athletics, I also firmly support the right of women to compete only against other biological women. That was, in fact, the first point that made me question my compete inclusion viewpoint.
I did not post before because many are expressing these beliefs in a much more articulate way, and also because I am concerned by how aggressive some of the posts are, but wanted to say that I have now moved on from a position of complete inclusion to a gender-critical position. You can say I have peak transed.
