@SarahTancredi
the scotish student expelled from school was boy...(saying there's two gender)
and i have heard story about boys protesting against gender neutral toilet.(but ending was bad i remember but still...)
i don't think it's just boy vs girl problem.
i'm pretty sure the school will make boys shut up for complaining about girls in boy's loo, too.
this topic is also matter to boys, girls, muslim ,hindu,christian, not religious but simply uncomfortable, sikh, asian, jews, white, orientals...
sorry i can't explain well...
