I don't normally recite the "Pledge of Allegiance," for two reasons:
I have allegiance to the people in the USA, but not to a piece of cloth. A textile assemblage is a symbol and perhaps a work of art—but nothing more. I would no longer pledge allegiance to a flag than I'd bow down before a statue or an emperor.
I resent the phrase "under God" that was added during Cold War fever in the 1950s. The USA is not a theocracy. We are not and should not be a nation under God.
