The phrase "Under God" was a late alteration to the Pledge of Allegiance, just like the currency motto "In God We Trust". Acts of Congress established them both
during the McCarthyism era of the 1950's. Contrary to being expressions of free speech, these alterations are violations of the Establishment Clause of the First Amendment­ violations of the principle of church/state separation. When the government does things like this, it is making claims of religious opinion on my behalf­­ something it has no business doing. The government is an entity, not a private citizen, and therefore it does not have the right of free speech; it does not have the right to have a religion of it's own. On the contrary, it is supposed to uphold the Establishment Clause of the First Amendment. It is supposed to protect unbelievers like me from those in the religious majority who would take away our rights. The government should never promote religion over non­religion, or one religion over another.
