Why
can't there just be single occupancy toilet rooms and urinal rooms with
an occupancy lock or symbol? It's humiliating enough to have to use a
stall or be near anyone while urinating, defecating, vomitting,
farting, or changing a tampon no matter what the "gender". It's
humiliating enough to observe odors or anyone's waste.
