So you can’t ask if someone has a GRC.
Being a convicted rapist is no bar to getting a GRC,
There’s no process to having a GRC rescinded, either by compulsion or voluntarily (as with Keira Bell, who would like to revert back to her sex, but I think cannot do so).
There is a presumption being made that a wrong is being done if any natal male person, who may or may not have a GRC (because you’re not permitted to ask) is denied the option to be in the female estate because of their identity.
So the policy boils down to the only bar between a rapist and a bed in a cell with a woman being their own better nature, based on the assumption that no one would lie about their gender identity?
I wonder, which sort of man would be motivated to lie about their gender identity?
And what actual, practical use is a GRC if it can’t be used in cases like this?
