Because we all need to be reared from little kids on that this is a nation governed by the Christian Coalition who tries to sell oppression as freedom and we must obey a set meaning of "GOD" that we all need to adhere to or we will burn in hell and hurt little children and break up families. So is "under god" a result of revisionist historians, activist judging or strict constructionism? I'd have to say it was the result of revisionist historians in Congress who added it to the pledge and activist judges who ignore the separation of church and state. Just the type of people the extreme right should hate.
