I have been pondering.
The whole premise behind “you may not ask disclose if someone has a GRC” and the presumed motivation for the GMC hiding previous names/sexes, has got to be the old-school idea that trans-identified people will always pass, and that it would be terribly distressing for them if anyone were ever to find out that they used to be “the opposite sex.”
But, other than some trans-identified women (because testosterone is a helluva drug), they generally don’t pass. So, at this point all this obfuscation is just out and out gaslighting of, well everyone. The trans-identified people know, we know, the powers that be know, but everyone (except the little boy who shouted that the Emperor was naked) has to pretend we don’t. It’s ridiculous. No, it’s bullshit.
Also, back to the Dentons document, and how best to sneak stuff in under the radar, I seem to remember someone from around these parts saying that when ITV introduced their trans-identified man character (Hayley Cropper) to Coronation Street, he was played by a woman (Julie Hesmondhalgh), the idea being that people would then have this woman in mind (rather than Pete the Plumber in a dress) when they thought of trans-identified men.
