Those of you who have seen old movies know that "under God" was not originally in the Pledge of Alligiance.  That phrase was added by Congress in the 1950's.  This is a petition, not to remove "under God", but to let each person replace it.  A Muslim would be able to say "one nation under Allah," a Hindu "under Krishna," and an atheist could say whatever they see fit.  Isn't that what America is supposed to be, a melting pot of cultures?
