Reading back over the thread, GreytExpectations, it seems you haven't addressed the issue of competing rights.
Again and again you talk about equality and caring about everyone's feelings. However you really don't seem to get that sometimes what one group demands is incompatible with the rights of another.
If men who identify as women say it's their right to access the women's changing room this disbars women from a range of minorities who cannot disrobe in the presence of a man other than their husband. By granting the demands of one group you strip the others of their rights.
And the protected characteristics under the Equality Act are age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation.
In the situation I describe the women are being affected on the grounds of sex, religion and belief. That's not acceptable. Gender reassignment is not gender identity.
This exact situation is currently the case with the women's pond at Hampstead. There's talk of a legal challenge to the decision to allow men who identify as women to use the women's pool.
Can you not see that in many cases what's being demanded by TRAs damages the interests of women (and men too, though to a lesser extent)?
Things like misgendering and deadnaming are far too big of an ask. Those insisting we observe this are demanding control over how they are perceived, in a way others do not. It's unreasonable and authoritarian.
It can be impossible to be sure what gender a stranger believes themselves to be and most people don't much care. Besides which, we mostly use third person pronouns in the absence of the person. Misgendering is actually correctly sexing - human beings, well all animals - are really good at discerning the sex of a stranger at a glance. Trying to shame someone for correctly sexing you is dreadful.
As for deadnaming, it hardly seems worth kicking up a fuss about, particularly on a forum where so many millions of us have changed or altered their name.
But of course some people have very strong motives to conceal their past. There have already been cases of sex and violent offenders who have tried - and in some cases succeeded - in concealing their criminal past by transition and a new feminine name. Cries of deadnaming now bring out the Miss Marple in me.
