I've skim read the more recent posts and not dismissing everything but wonder if it wouldn't be more helpful to discuss outside of the ERCC case, because we know that workplace is politically motivated by a TRA agenda.
One issue is data protection which is about date stored by an employer or membership organisation which should not be attached to a name anyway.
The second, which I think is more important, is how in relation to service provision or say a gym or swimming pool which advertises women only services.
Because it is advertised as such surely the potential client or user can ask that someone is either male or female as per the SSE in the EA, ie can only be biological sex, and explicitly excludes those with a GRC or in the process of applying to a GRC.
And the provider must answer honestly, and if they try to include anyone other than of the relevant biological sex then they are not only lying but opening themselves up to causing distress to the potential user / client.
It comes back to another aspect of what is happening in the world at large (or at least in the UK) which is that the SSE exist, and any number of groups, institutions, companies could use it but choose not to.
So it isn't about who could claim to be the sex they are not, or even that they dont have a sex, but why so many organisations so totally fail to respect women's sex based rights that they dont implement it.
No amount of campaigning that has happened in the past decade or so has changed the mind set that women's rights are of equal importance.
Even though recent court cases have said in relation to employment, that differing beliefs must to equally respected. So if some want women only and some want some hybrid women's provision then the employer or provider has to cater for both. They cant say we will only bother with one.
It is just another area of women's lives that have been eroded.
Many of us (not just oldies) grew up at a time where it was natural to have single sex provision. Not everything from this previous era has no value.
Maybe the Minister for Common Sense could wade in and stop so many people thinking that young people (not forgetting that men aren't thought to have matured until 25) can dictate how everyone else should live.
