I'd actually be very happy for loo's to be called URINALS and TOILETS.
Those with a penis can use the urinals. Those without can use the toilets. ( Just the same as we've always done - but without labels!)
I actually think that taking away the M/F element and de-gendering would be a good thing, as it would take away the fetish element.
Most importantly, it protects the vulnerable and solves safeguarding issues.
It also has the huge bonus of helping the genuinely gender dysmorphic feel more comfortable about not having to use the "wrong" loo for their adopted gender.
If you have a penis, whether a male or a "female" one - you should be using the Urinals. Anyone who feels unsafe can use a unisex disabled loo.
I really like it. It would stop people with dicks being in people without dick's areas. Awesome. Much better idea than "identifying" which loo you want to use. I like it.
I think we should start a campaign - anyone with a penis is not allowed in the non-penis areas ( regardless of gender)
Oh wait.....
