"The standard you walk past, is the standard you accept." --Lt. Gen. David Morrison, former head of Australian Army.
Amusingly he was talking about a situation where male soldiers were sexually assaulting female soldiers, while a larger group of servicemembers knew this was happening but did nothing to stop or report or prevent it.
He's 100% right though. The standard this school board walks past, and thus the standard they accept, is one of their own sexually harassing a teenage girl.
Every one of them that laughed or snickered or whatever should be removed.
