About 15 years ago there was a Belgian movie entitled Ma Vie en Rose (My Life in Pink). (Outstanding movie, by the way; catch it if you can) There was one scene in particular in which Ludovic, a transgender girl takes a boy into a bathroom to prove to him that she's really a girl. What really did a double take was the fact that the bathroom was just that - a bathroom, not a boys room or a girls room. Separate bathrooms were just a silly nuisance and an exorbitant expense. (Funny how Tea Partiers will slash and burn on one front, but insist on separate bathrooms - maybe if we squat over a trench...)
