Of course it's even more ironic and laughable that many Trads (especially SVs) embrace a broad understanding of BoD (beyond St. Robert's limiting of it to catechumens).
See, the problem is that if you accept this broad definition of BoD, then the Vatican II "errors" are merely logical conclusions of your own theology, and you have absolutely no business opposing them ... and are in schism for doing so.
If various non-Catholics can be saved, since EENS (dogma), then these various non-Catholics must be "in the Church" somehow. There's no getting around that. Consequently "the Church" consists not only of actual Catholics but of all manner of non-Catholics who are in the process of being saved. This is precisely V2 subsistence ecclesiology in a nutshell. It's not even remotely difficult, a most basic syllogism. But these people remain in a state of cognitive dissonance, wanting to have their BoD and reject Vatican II also (for basically teaching the same thing).
In addition, if one saves his soul by the subjective process of believing in (some kind of) "god" who rewards the good and punishes the wicked, and by doing the will of this "god", i.e. by following the dictates of even his false religion, then, since he has a right to please God and save his soul, then he has a right to observing his false religion, so that even Religious Liberty follows directly from this. If you impede him from doing the will of this "god", as he sees it, you're actually jeopardizing his salvation.
And, when Bergoglio stated that all religions are ways to God, how is he wrong? You guys agree with him. See, if people are saved by believing in the Rewarder God and doing his will, then any religions that inculcate belief in a Rewarder God (which is the vast majority of them) and encourage people to do his will are in fact ways to salvation, just like Bergoglio says.
So these Trads (SVs) in particular, never cease to bloviate about these "heresies" of Vatican II and Bergoglio ... while believing and teaching the same damnable theology themselves.
It would be laughable if it weren't so tragic.
