If you put any moral obligation (i.e. under pain of sin or heresy) on anyone to believe sedevacantism, (in any form, in any degree), then you are extreme and dogmatic.
If you put any moral obligation (i.e. under pain of sin or heresy) on anyone to believe R&R, (in any form, in any degree), then you are extreme and dogmatic.
No catholic, anywhere, has to accept either sedevacantism, sedeplenisim, R&R, etc, etc. There is no moral obligation to even make a decision on the matter (except for the hierarchy, whose job it is to protect the Faith and if they don't clear up these matters, they will be judged on that). The only moral obligation that trad catholics have is to 1) follow the 10 commands and laws of the church and 2) believe all those dogmas of the faith which the Church has taught us. The issue of the papacy is a fun and interesting topic to discuss but that's the extent of it. One can easily stick with tradition and ignore the papal problems and save their soul. God's not going to ask us on judgement day of our opinion on the pope (because our opinion is meaningless). He's going to ask us how well we loved Him, by keeping His commandments and keeping the faith. The problems in rome are no one's to decide or fix, except the Church. And none of us in tradition are the Church.
