I found these quotes from Stubborn, but I apologize to him because it seems that he has restrained himself somewhat from speaking badly about his popes:
”Bergoglio and all the conciliar popes have been heretics.”
“he helped that whole treasonous effort, he left the fate of the whole world in the hands of Paul VI, Bugnini, JP2, and etc., etc.
If you can blind yourself to what you think Siri actually did, then think he would have been a better pope than Paul VI, then I can say that Paul VI was most likely the lesser of two evils. . .while being mindful that it could also be that Siri may well have handed the baton to Paul VI knowing that Paul VI was a better destroyer than himself.”
Glad you realized that stubborn generally refrains from saying much about the ill-deeds of the conciliar Popes.
I think that it's illogical that a sedevacantist can say whatever he or she thinks about a heretic pope, but they don't want non-sedevacantists to do the same.
By this logic, a non-sedevacantist wouldn't even be able to consider that a pope can be a heretic. Therefore, you should never engage in conversation with a non-sedevacantist.
Or, perhaps you can say to a non-sedevacantist: "I can say whatever I like about the heresies of the non-Pope, but you are not allowed to say anything about the heresies of the so-called Pope, because you actually believe that he is the Pope."
Do you see how this could be a problem?
