It is terrorism... nothing to do with the First Amendment...
Terrorize people by attacking their children when they are at school... molest their minds first... then they will molest their bodies later...
All the school administration need do is ignore the physical assaults by the purveyors of perversion and they can have both.
It has been done before with different issues and 'protected' groups, this is no different. The school employees can always fall back on the 'protected group' status to excuse the inexcusable, a ready-made cop-out.
Anyone's child's best defense is the deep understanding that their child can come to them with their problems, regardless of what is said by whom in the school. Then, it is up to the parents to act.
