No, it's not what you're thinking.
A working group in Vancouver (and no doubt other bodies elsewhere across the country) is
struggling with the issue of gender identity and bathroom iconography.
Basically, they're trying to figure out how to accommodate the biological needs of trans-gendered people in the traditionally male/female realm of bathroom labelling.
So far, the best they've got is a new 3-room icon system: one showing a shower (where you can shower); another showing a toilet (where you can relieve yourself); and a third showing a clothes hanger (where you can presumably hang up your jacket or obtain a cheap abortion).
I'm all for inclusivity, but this debate causes me some concern. My number one worry is that they'll get rid of urinals under the new regime, whatever it ultimately ends up being, because they're gender exclusive. That would be a tragic loss to men (who will have to touch stall door handles and other grotty bathroom stuff, not to mention the loss of peeing efficiency) and women (who will now have to trust the guys who used the toilet before them to have lifted the seat or have aimed impeccably - neither of which we're likely to do, particularly since the loss of our urinals will have filled us with spite and nihilistic rage).
But what form of universal bathroom system could work for everyone?
How many different rooms does the species need?
How should each be equipped?
And most importantly, what signs should we put on them?
Serious answers only please, as I need this for a school project.
