4. Dozens of Catholic bishops and hundreds and maybe thousands of priests have already publicly declared that Jorge Bergoglio's claim to the papacy is invalid.
Are there really thousands of priests who have publicly declared that Francis is an antipope. That seems to me like something you just said with no evidence that isn't true. If it were true there would be thousands of sedevacantist priests. Are there really that many?
There are at least 40 Catholic bishops who have publicly declared that the Conciliar popes are antipopes. Here is a list:
Bishop Robert McKenna, OP
Bishop Franco Munari
Bishop Philippe Miguet
Bishop M. Main
Bishop Richard Bedingfeld
Bishop Oliver Oravec
Bishop Joseph Corona Santiago Gomez
Bishop Peter Hillebrand
Bishop John E. Hesson, OSB
Bishop Mark A. Pivarunas, CMRI
Bishop Javier Miranda Chairez
Bishop Daniel Dolan
Bishop Clarence Kelly
Bishop Edward Peterson
Bishop J. G. Roux
Bishop Michael French
Bishop Camille Nziboe Mebale
Bishop Xavier Alain André du Rosaire
Bishop Raphaël Cloquell
Bishop Francis Slupski, CSSR
Bishop Martin Davila Gandara
Bishop Geert Jan Stuyver, IMBC
Bishop Donald J. Sanborn
Bishop Robert L. Neville
Bishop Giles Butler
Bishop Andres Morello
Bishop Joseph J. Santay, C.S.P.V
Bishop J. Rodriguez
Bishop Luis Alberto Madrigal
Bishop Paul Petko
Bishop Robert Dymek
Bishop W. Greene
Bishop Bonaventure Strandt
Bishop Emmanuel Korab
Bishop Thomas Fouhy
Bishop José Ramon López-Gastón
Bishop Terence Fulham
Bishop John Simmons
Bishop Markus Ramolla
Bishop Neil/Dominic? Webster
There might be more.
As for the number of priests, I do not know but you would be sadly mistaken if you tried to claim that there are less than 200 sedevacantist priests in the world.
