Again you are (mostly) correct. However, NC and SP do have a relationship and I'm sure NC will have conveyed her views to Sandie and will be available if Sandie asks for her opinion.
I'm never sure which side you are really on. You seem very quick to be pedantic on the tiniest points. This often comes across as you being supportive of the trans rights side. Which is your prerogative.
But as an example you jumped on me when I was talking about single sex spaces on another thread by insisting that the SC judgment referred to single sex services. As is clear to everyone, providing a single sex space is a single sex service.
I don't actually understand why this point mattered so very much to you, but it came across as if you were arguing about the number of angels dancing on the head of a pin (a metaphor for wasting time debating topics of no practical value, or on questions whose answers hold no intellectual consequence when more urgent concerns accumulate).

Is it your pedantry or your opinion? If you are a lawyer, say so.
I am always willing to correct my mistakes, but it is very disconcerting to be pulled up on my posts when it is clear what I am trying to convey. And I am someone who enjoys my own pedantry.
Are you trying to waste time debating things of no practical value, or is this just your way?
