There are no disabilities or cultural reasons for single sex loos.
Seriously. We're going to do this.
Ok.
There are no male people who identify as women and want to use women's spaces.
There is no such thing as ice cream.
Boris Johnson doesn't exist.
None of those things are true either, which makes it pointless to say them.
Unless you're keen to do a Donald Trump/Putin, there really is no point in just denying realities you don't like and don't want to exist.
There are women all over threads here who have repeatedly, multiply explained:
YES females are excluded on grounds of disability, culture, faith, belief, trauma (probably and very likely would also be covered under disability on those grounds). Sorry, really sorry these women are causing challenges for male people getting their own way, but we are not making these things up for fun for goodness sake.
Female people have to have equality of access to resources too
Many female people cannot have access if male people are in the space. What legal certificates and what labels and feelings those male people have do not make a difference to this
Male people are going to have to accept that not everything is all about them, and inclusion and access applies to other people too, and they cannot have this 100% their way and just disappear females with inconvenient disadvantages and challenges cos only female
And this all proves, in stereo, to the last decimal place, exactly why females need single sex spaces. Because in mixed sex spaces everything, constantly, is all about males, who dominate the agenda and prevent female needs from getting met.
Have third spaces. Have ninth spaces for all I care. Gold plate them. Serve bloody caviar on rollerskates. You do not get to just declare females who cannot revolve around service to males do not exist and therefore don't matter (and therefore males can have everything and it's fine.)
You're trying to salve your conscience. Think it through. Either you are into access, equality and kindness - which I'm sorry, does mean everyone and not just you and your mates and requires mutual tolerance and a range of provisions to work for said everyone - or you are into male supremacism. Which is it?
