You keep parroting the same refrain "they have been doing it in public schools for the last twenty years" What you ignore is that it was kept secret ..the public was not informed, or you would have had the same reaction two decades ago... non-muslim teachers did not like it, teachers old enough to remember the banning of the lord's prayer, certainly did not expect it to be replaced by muslim prayers. The fact that it was going on for twenty years does not make it more palatable so stop.
