You educate them and expect them to act like the ****ing adults they're supposed to be, to follow their orders and not deviate from them for any pansy "personal reasons." You give them strict instructions and allow for one or two "oopsie" moments, so no one can cry foul about how awful and harsh it is to have to suddenly behave like a grown up. After that, they're out. If it means we ****can a bunch of bad apples, so be it. Do we really want a bunch of whiny and/or violent homophobes on the force anyway?
Just do your damned job and get over yourself.
