Ok, ja visi tik filozofiski pieiet dzimtēm, tad nošķiriet toletes pēc sex not gender, un ja tas nestrādā, tad nošķiriet mentally challenged and mentally sound people tualetes. Or just be very specific and make toilets for people with authentic vaginas and penises, and toilets for artificial vaginas and penises. I mean you cannot argue with that, and if you do, then make a third toilet for people who cannot tell the difference between natural and artificial.
