Well, that's the problem ... will R&R ever get to this point? That's why I indicated that the first order of business would have to be cleaning this up. If I were Pope and, say, condemned Baptism of Desire, R&R would just "resist to my face" and some SVs would declare the See vacant due to heresy. THAT epitomizes the problematic fallout from some of the Traditional Catholic positions. Those would need to be addressed first, because we need the remnant Traditional Catholics to spread Tradition back to the rest of the world. That is why Bishop Williamson referred to the Traditional Catholic movement as a "pilot light". It's a great metaphor.
This is the reason why I think invincible ignorance and BoB/BoD is more important than the sedevacante question.
