Beyond a passing thought, there is no reason to question papal occupancy / vacancy to the point of making the idea of sedeism foundational to your faith, which is the situation that you are in. False canonizations happened for a reason - to deceive everyone and anyone who allows themselves to be deceived.
Absolutely you have to question the papacies of the V2 papal claimants. If you question the canonizations, you must question their papacy. Otherwise, you're questioning THE PAPACY as an office, its protection by the Holy Ghost and the Church's protection by the Holy Ghost. You throw the entire Papacy under the bus, and the Church under the bus, in order to preserve the individual papacies of Roncalli, Montini, et al.
You attitude toward the Church, that the Papacy can become corrupt and require the faithful to separate from it is different in no way from the claims made by the Old Catholics, Eastern Orthodox, and Protestants. Each of these heretical/schismatic groups claimed that the Papacy had veered off the path of True Christianity, for the Old Catholics and Eastern Orthodox, from the path of Tradition ... and you follow them into heresy and schism.
You either have to accept the Conciliar Church as essentially Catholic or you have to reject the claims to the papacy made by the V2 "popes". There's no other alternative if you wish to keep the Catholic faith ... which you are in great danger of losing, if you haven't already lost it. Barring allowances made for subjective confusion on your part due to the Crisis, you would have to be treated as a manifest heretic and excommunicated from membership in the Church.
I've pleaded with R&R to consider the position articulated by a Father Chazal (whom you still consider R&R), and yet you pertinaciously refuse to do so. Or at least adopt the attitude of Archbishop Lefebvre, where he stated clearly that 1) this degree of destruction is incompatible with the promises of Christ for the papacy, the protection and guidance of the papacy by the Holy Ghost, 2) that it's possible that these men are not popes, 3) but I'm not 100% sure what's going on, so I defer to the Church's judgment. But you reject principle #1 above, which puts you into a state of manifest heresy and schism.
