“”Unitarians, Seventh Day Adventists, Jehovah’s Witnesses, Mormons, Hindu’s and Buddhists” do not, as a rule and practice of their faith, slaughter Protestants, as Rome does.”
Of those groups the only one I’m aware of that will not slaughter anyone at all (Catholic, Protestant, whatever) is Jehovah’s Witnesses.
btw, did you follow that error of yours in thinking there was only one limbo? Perhaps it would help to check the other areas where what your group may believe and say about The Church are wrong?
