All of you arguing about R&R vs Sedevacantism are missing the point. Just as no Catholic leaves the Church for Protestantism/atheism because of doctrine or theology (99% of the time it's because they want to escape Catholic morality), nobody leaves Traditionalism for the indult because of theology/doctrine (i.e. R&R vs Sedevacantism). The reason Trads leave the True Faith for the fake 'indult faith' is because of the 3 dangers we all must face - the world, flesh and the devil.
.
So the usual temptations that Trads face are
1) Being considered "extreme" or rigorist (i.e. peer/social/family pressures...temptations of the world)
2) Dating/morality/marriage temptations (i.e. temptations of the flesh).
3) Temptations to despair, feeling alone in your Fauth, feeling abandoned by God/Church, etc (temptations from the devil)
I believe this is quite true for your average lay Traditional Catholic ... but not for a Salza and not for most priests. I myself went through the same process in seminary that many priests and seminarians did. You start off as a Traditional Catholic mostly by recognizing how contrary Conciliar Catholicism is to Tradition. You tend not to go too deep into it. Stubborn is still at this phase. But then you start studying Traditional Catholic theology, in particular ecclesiology, and it hits you in the face how contrary to Tradition R&R really is. Then you’re faced with a choice to resolve this somehow. Those who did not experience such an intellectual process were, quite frankly, either somewhat dull-witted, or just didn’t care much about “theology”, writing it off as irrelevant compared to learning how to say Mass or give sermons or hear Confessions. You’ll notice that sedevacantists tend to be the brightest seminarians and priests.
