Basic facts here:
women who don't object to mixed sex toilets (and by extension changing rooms, hospital wards, rape crisis services, refuges, denial of same sex health care professionals even post rape, and being strip searched by a man who identifies as a woman, the use of the word 'toilets' just hides and trivialises all the rest of the package) will be happy in the gender neutral additional toilets.
The women who do and are reliant for access to society on single sex, can go on having single sex.
Everybody happy, equality of access, wtf is the prob Burnham?
Why deride and attempt to silence those women? The ones who would have nothing at all and no access to society (mostly from minority groups) if all women's spaces are for men? What is the point of that?
