If you ask me, turning the papacy into a cardboard cutout is precisely what R&R do. You can see pictures of the V2 popes in SSPX chapels, but that's the extent of their submission.
SVs just say that these guys aren't the popes. What are they, Father Chazal, if they're wakling around but don't have authority? Zombie popes?
R&R: cardboard
Fr. Chazal: zombie
SV: dead
