Why do you think she says that Dadjoke? She's a legal mind who disagrees with noted TRA Alex Sharpe that it's not possible to have single sex spaces, which is what you asked for. There are about fifty thousand threads here which have discussed the legal position around single sex spaces, sometimes TRAs have popped in to tell us we are wrong, but legal opinions vary, as pp noted. Do some reading.
She is not disputing the law. She is suggesting that organisations make use of the exceptions permitted. My point was simply that it's exception-based, and the default is inclusion. Neither interpretation disputes that.
Sharpe does not say that it's not possible to have single-sex spaces, merely that there's a high bar, although it hasn't been tested. That's a point of dispute, I imagine.
I've read the GRA, the EA2010 and some legal interpretations. The article you pointed me at isn't a legal interpretation, it's advocacy which accepts the reality of the current law.
If you are willing, and you know of an article which disputes my postion that it's inclusion by default, with exemptions, I'd be grateful to read it. I completely understand if you can't be arsed.
