There's a reason why society calls the facilities the "rest room:" the de-emphasis reflects that this is a private necessary function that really isn't suitable for a sexual politics battleground. Even when men stand at unpartitioned urinals there's an etiquette of privacy. Sad that an arrangement that traditionally allowed both sexes a few moments of privacy (or socialization when gaggles of women troop to the rest room together!) has to be turned into a grievance issue, or risk that somebody of the other sex can wander in by saying they think they're a girl or don't have any gender. Not saying there are no such people: just saying that it ought to be possible for everybody to do their business without a huge fuss. I have a shrewd suspicion that Trans folk who made the physical change, would agree that there is no fanfare when they go into the facilities- and nor would they want one.

What about changing rooms at the municipal swimming pool?

/edit/ doesn't really matter what I think. Here's what some college kids in Washington think:
