Yes quite goady! 
I do agree with it though that the Equality Act and self ID are two different things, but I don’t think anyone has ever argued that they aren’t?
What I’m saying is that they interact with each other.
So, using Bespins example we have the NHS which has 2 transwomen employees. Employee A has a GRC and has therefore lived for at least 2 yeas as a woman, has a diagnosis of gender disphoria and most likely has had some form of hormonal/ surgical treatment for this. Employee B on the other hand does not hold a GRC. Employee B is just at the beginning of their transition and has only changed name and pronouns.
At the moment, as Bespin has stated, if a female patient requests a female nurse, the NHS would apply the exemptions with regard to employee B, but not with employee A. As far as the NHS is concerned, employee A is female and the NHS can’t ask to see a GRC.
So then self ID comes into law. Employee B, who has no gender dysphoria diagnosis, has made no steps towards transitioning other than a name change applies applies for and is granted a GRC.
Before self ID: NHS would apply exemptions to employee B
After self ID: NHS would not apply exemptions to employee B.
Would you agree with my reasoning about how self ID and the EqA interact daim?
