As the late, great Christopher Hitchens put it, “Religion Poisons Everything.” The Earth shrinks in the eyes of the faithful – you may be relative newcomers like the Lhotshampa or residents older than the usurpers, like the Hindus of Pakistan or Parsis of Iran, or its just that you had a new idea, like the Baha'is or Ahmadis. Only a secular republic will recognize every single inhabitant as its own.
