You are correct. But I would like to point out that the sede interpretation of Bellarmine is actually incorrect. Bellarmine argues R&R - He said a heretical pope should be "resisted" and "who will depose him since he is a sovereign?" and "an ecuмenical council cannot even do it". If you don't believe me, then go read the pertinent chapters of "On the Roman Pontiff"
Yet here we have laymen who will depose him, and uncharitably attack those who actually hold the position of the Saint they claim as their own. Others take it even further and make it a new dogma that you must hold and even change the canon of the Mass. How isn't that the slyest manifestation of Modernism in existence?
All this over what? As has already been pointed out ad nauseam - there isn't a practical difference between the R&R and sede approaches to the crisis. R&R already knows that Rome has lost the Faith. They already operate outside the Conciliar Church. Maybe the sedes should go bark at the local Novus Ordo church, or FSSP if they want to evangelize. But I have a feeling evangelization isn't what this is really about...
It's about intellectual pride; about being right more than anything. And this isn't just found on one side either, it's present on both. Which is why we can't agree to disagree until the restored Church settles the matter.
SperaInDeo nailed it, and DigitalLogos has a great reply, and I'm willing to be corrected here, but I disagree that
"this isn't just found on one side" because it is the sedes who are the ones out to prove the impossible, namely, that their opinion is most likely true, or that their opinion is indisputable fact, or heck, some sedes even elevate this opinion as being a divinely revealed dogma. And since this fact of sedeism has somehow eluded R&R, then R&R need to be convinced about it so they can accept that the heretic claiming to be pope is not the pope.
Meanwhile, R&R fend off the opinion attempted to be forced on us and simply accept the indisputable fact that aside from
keeping the faith, praying for him and not listening to him, there's nothing more we can do about heretical popes.
What is the risk to salvation for RnR if they're wrong, and what is the risk to salvation for sedes if they're wrong?
