They were also called Anti- Christ or Heretics. The 16th century reformers were called "Protestants". Scientologists call their adversaries "SP" or Suppressive Person, I think. The Mormons call their attackers "Anti-Mormon. Help me with the list. Are their names the Amish use, the Muslim uses for those who are "whistle blowers" against them, so to speak? I mean the list is long. Baha'i? Buddhist? 7th Day? Help me out.
