We are living in very sick times. There was a time when parents would march into the administrators office and raise hell over this. But sadly we live in a time where the sicker and more disgusting a movie or song is the better we like it. We allow Netflix and HBO to dump filth into our homes and we say nothing. Soon when a parent stands up and says no! my daughter will not shower with male teachers and coaches that parent will be called a bigot.

Less than .3% (that's POINT THREE PERCENT) of human beings are transsexual and even fewer are using school bathrooms.
Its possible that the VERY occasional trans peed next to you and you never knew it. The bigger concern is the sickos checking people's pee pees instead of minding their business. Now THAT is really very sick.
If you're really afraid of men in dresses assaulting children, why aren't you going after priests and the catholic church that hands over their victims?
