How long before we can do away with gender specific spaces?

Well, I have to disagree, as it is, it's inherently broken. While protecting women from whatever it is hetero men might do, it's endangering those same hetero men by exposing them to homosexual men.

We either need to add a whole lot of restrooms (het men, homo men, het women, homo women, trans mtf, trans ftm)

Or reduce to just one for all.

To say it's not broken is to ignore these realities.

Well, that's certainly one point of view, but what about all those anxious homophobes that are worried about the guys seeing them in their state of vulnerability.

Or those vulnerable women that are just trying to do their business with a degree of privacy and in walks a man in a dress that claims that even though he's male he "feels" like a woman so they should just accept his presence in their safe female sanctum?

I'd say it's damn well broken right now.

If you wanted to execute the gays and not allow transgenderness than, yes, it's not broken, but that seems a little extreme.
