How is this different than the Yankees having a no beard rule and the Army having their own hair regulations?
This thing was blown way out of proportion for no reason at all. Per my wife, her school had these rules 20 years ago in Brooklyn. Can you imagine what would happen if someone videoed a chassish school! All of a sudden my frumkeit has to be everybody's frumkeit on the same exact level.
Seems like the general societys way of thinking is rubbing off on us as well.
(in this case, the ruler was brought by the parent)
