Yes, for every thread telling Catholics they should leave their church, there must be more than one hundred threads celebrating Protestants who convert to Catholicism.
And the nutty thing is that no seriously taken leader of any sect, Roman Catholicism, Orthodoxy, or Protestants hold that the others are hell bound.
For example, I do not believe for a minute that Mary popped down into a cave outside of Mexico and told the Indians they should be catholic. No more than I believe Jesus did the north American tour as the Mormons say.
But though I do not believe it, I do believe those Mexican Indians belong to Christ. I cannot see why this topic generates such heat, and little light. None of the leaders advocate it except the nutty fringe.
