You want to defend sedevacantism, and there is nothing that I can say that is going to penetrate.
And, no, I am not interested in defending sedevacantism. There are differing theories about what happens to a heretical pope.
What I AM interested in doing is to defend the Catholic Magisterium and the indefectibility thereof, along with the indefectibility of the Church's Universal Discipline ... and the general Holiness of the Church. Unlike yourself, evidently, I believe in one HOLY Catholic Church. Does that expression ring a bell?
