I don't think that men's and women's toilets have the same roles in our western society. Being an actual toilet is just a small function of this role.
Dignity, privacy, safety, and even a social gathering space are all features that women want from public toilets. Of those, arguably the most important is security and that's the main issue to raised by the enforced sharing of the space with those who weren't born female.
But there may be some good reasons why men don't seem to attach much importance to these features. Dignity, privacy and accessible space is not something you'll find much of in men's public toilets. I should know, I've cleaned a few in my time.
There's a lot of wet mess and smell because the men have to stand up and splash their pee down the side of a common trough that runs into an open gutter of pee right by their feet. They have to get used to being shoulder to shoulder with other men while they pee. There may be some cubicles there, but far less than you'd expect to find in a woman's toilets.
I worked in a company where the women's toilets were clean, airy and spacious and had tables, vases of flowers, mirrors, chairs and windows. The men's toilets, however, were little more than a grim, windowless cell, devoid of any trappings other than a trough, a sink and a single cubicle. I presumed that the men didn't complain because it didn't bother them, but it could be because they never actually knew about what the women had going for them. Why would they?
And men's public toilets are often cleaned by female staff. The toilets carry a "warning" sign on the wall saying as much, but is usually displayed inside, rather that on the entrance. And if they don’t like the idea, well that's just too bad - they can go find another toilet.
We would be horrified and mortified if such conditions were imposed on us. Being told that a man may suddenly appear in the ladies toilet, several times every day without warning, to carry out maintenance or something would be quite unacceptable.
So, minimalist toilets appear to be no big deal for men. But maybe if we raise the profile of ladies loos, they might wake up and start demanding better ones for themselves!
Now you'll have to excuse me as I need to go outside and squat in the bushes.
