I have no expertise in the legal issues here, but I was struck by a recent case in Wheat Ridge Colorado. A seventh grade teacher took out "under God" from the pledge and replaced it with "One nation, under your belief system...". This doesn't make sense even for extreme relativists. The teacher claimed to have been influenced by the sixth anniversary of the Columbine shootings (double huh?) and the need for all-inclusivity. The principal sent home a letter of apology to all parents.
