In my interaction with fellow Catholics on a daily basis @ the parish level ... it is Kung who rules the day ... and this is what fuels the traditionalist movement.
Then it is sad to say that those fellow Catholics are all buying into heresy.
Kung has been stripped of his license as a theologian by the Holy Office when it was headed by then Cardinal Ratzinger serving the actual Roman Catholic Church (headquartered in the Vatican and not at Wittenberg or Econe).
What ought to fuel the SSPX schism is those little burning sticks under their disobedient feet as they burn at the stake. Oh wait, that was in far more actually traditionalist times when obedience was part of tradition.
Another soul to wherever from Torquemada's band!!!
