As you know, there is a litany of defections from the SSPX from the day of its establishment, to the left of Conciliarism and to the right of Sedevacantism. Which way did you go again???!!!!
That is understandable given the nature of this crisis. Catholics who have the faith cannot NOT have a tension between the need to be in communion with and in submission to the Catholic hierarchy. There's no pre-Vatican II teaching, no Pope, Church Father, Doctor, or theologian who ever held that it's OK to break from communion with and submission to the Catholic hierarchy. That was the stuff of Old Catholicism, Eastern Orthodoxy, and Protestantism. So this tension tends to resolve itself one way or the other, by either trying to reconcile the post-V2 changes as accidental, perhaps destructive due to its implementation rather than its substance, and therefore return to submission to the Conciliar hierarchy, or else, if one is unable to apply this "hermeneutic of continuity" to the V2 changes, to hold that the Conciliar hierarchy is not actually the Catholic hierarchy.
So, basically, if the crisis were characterized by a syllogism (from the SV perspective to start):
MAJOR: Catholic hierarchy cannot substantially corrupt the Magisterium and the Mass.
MINOR: Conciliar hierarchy substantially corrupted the Magisterium and the Mass.
CONCLUSION: Conciliar hierarchy is not the Catholic hierarchy.
SV: hold the MAJOR, MINOR, CONCLUSION
R&R: hold the MINOR but tend to reject the MAJOR and therefore the CONCLUSION.
Conservative Novus Ordites: hold the MAJOR, reject the MINOR, and therefore the CONCLUSION.
Some people refuse to accept the CONCLUSION out of hand, and so they struggle with whether to reject the MAJOR or the MINOR to avoid the conclusion. R&R reject the MAJOR, while those who end up back in submission to the Conciliar hierarchy reject the MINOR. SVs reject neither the MAJOR nor the MINOR, and so they end up at their SV conclusion.
