In the High School where I taught, the only gay teacher stayed in the closet. It was years later when the adult boys came out against him that we learned what went on late at night in the performing arts center with the head of the drama department.
If he were openly gay, the school would likely have put a watchdog on him during these after school hours. As a male teacher, I was taught to never be alone with a female student without the door being locked open. BTW, the city now has a policy that extends to all groups who work with the young. Attendance at child molestation classes is mandatory, and they learn what to look out for and how to conduct themselves. Never any adult child situations without a second adult or child present too.
That's a good policy. We have a similar policy when working with kids at church, which accomplishes at least two tasks. One, it helps to prevent any inappropriate action and two, it helps to prevent false accusations. This may sound strange to some folks, but I won't be in a house alone with another woman that's not my wife or not related to me, for some of the same two reasons above.
I think that's a good policy, for the protection of both parties.
