Maybe they should require these gender confused assholes to have their preferred gender and associated pronouns tattooed across their forehead to avoid conflict.

/——/ They would need washable sharpies instead of tattoos since their genders change at a moments notice.
They could get signs to pin to the fronts of their shirts. Just pick the sign that reflects the "reality" you feelz today.
Or hey, hang dry-erase boards around their necks. That way, they're prepared if they suddenly feelz something else after lunch. Or, y'know, if the line in one bathroom is too long and they suddenly feelz they are whichever gender will let them pee sooner.
