fascicle so as you yourself say, you both need and dont need a grc to access a prison of the opposite biological sex - in other words, they say you need a grc but it turns out you dont.
Not what I said at all. You said:
Conversely, you can be treated as the opposite sex by public institutions such as the prison service without having a gender certificate for that gender, but by getting a boob job.
So your highly misleading claim was based on the prison swap of just one person without a GRC - Tara Hudson. Somebody who in addition to 'getting a boob job' had accessed the services of a gender clinic; had had surgerical and hormonal treatment; had identified as a woman for years. Even your article concedes: 'He (sic) may or may not pose a risk to female inmates – we simply don’t know.' So, essentially, the objections to Tara Hudson being housed in a women's prison were nothing more than conjecture. Hudson has now been released from the women's prison where she carried out most of her sentence with no suggestion of any incidents on her part.

I was talking about using the law as a point of reference not as a comparison to transgenderism 
But now I think about it the comprisons stand up, slavery, rape and discrimination were legal because of thoughts based not on facts or evidence but societal norms.
It's hard to believe that your juxapositioning was accidental, especially since you have now developed the comparison. In what way do you consider that the legislation of rights for trangender people is based on societal norms?
There is no evidence for a male or female brain yet the law is willing to accept this because the law is not based on empirical evidence but reflects the thoughts and views of society (or those who hold power)
How is 'a male or female brain' relevant to the debate, and what proof do you want to accept transgenderism? Thankfully in the UK the decriminalisation of homosexual acts, and the shifting of societal attitudes towards acceptance of different sexual orientations, has not required the evidence you seem to want for transgenderism.
