Then I'm afraid you're being duped; the 'toilets' is always what's mentioned because many people like you will not know about the situation in depth, and so find it trivial, and so not resist, not realising that if men are legally permitted to be women in some situations, then all the rest of the things Mrs O lists are open to them too. It's a whole package deal. You can't have selected bits of it.
And it's lovely that you personally aren't affected by mixed sex provision, you'll be fine in the mixed sex gender neutral facilities, won't you? Very nice for you.
I'm sure though that you're not advocating that women who aren't as lucky as you and do have barriers to being able to access a mixed sex multi cubicle space should just be discarded and left without any access at all? In order that men can have their favourite preferred choice of all the facilities?
