These "Catholics" are very heretical, anyway. They will
(correctly) delcare Joe Biden, Ted Kennedy, etc
Catholics for their belief in abortion, etc. Yet they
ill not apply the same logic to the clergy or papacy.
These are not just simple mistakes in theology by the antipopes. Jorge Bergoglio said himself that he doesn't care if what he says is heresy. Genuinely, any evidence you show them they will deny, because they are blinded by emotions, a sense of community, etc.
