Is it possible to differentiate between a post-op TS with hormone levels in the female range, and a bloke who gets sexually excited by going into women's spaces? If not TS people are in deep trouble.
A male who has gender dysphoria and has taken medication to block testosterone as well as taking cross sex hormones and having one or more plastic surgeries has hormone levels within the range expected by these interventions for their sex.
Just as a male with some specific cancer diagnosis who has had surgeries and medical interventions invoving hormones, chemotherapy etc will have hormone levesl within the range expected for their sex following such treatment.
Some of these may be more comparable to the average female levels than male. This doesn't make them women/females any more than the man who has had radical treatments for his cancer.
'A bloke who gets excited by going into women spaces' (as described in quote) can identify as a woman, expect her female colleagues to share intimate spaces, report hatecrime if her preferred pronouns are not used, change the sex marker to 'F' on a passport, if convicted of a crime requiring imprisonment be placed in female estate, have that crime be recorded as committed by a woman, use 'single sex' female accommodation (wards/showers) in NHS hospitals, stand on 'all women's shortlists' etc Whilst describing her that way might earn me a deletion /strike on Mumsnet if reported.
Transwomen such as this don't need a GRC to do these things as its not neccessary.
