I think every single organisation will have the occasional infiltrator and one individual cannot mean the whole SSPX is compromised. If they were truly compromised they wouldn’t be ‘excommunicated’.
So ... that's a false dichotomy. Certainly the majority of SSPX priests are not infiltrators. But to get the "whole SSPX ... compromised" as a group, it takes infiltrators and/or controlled assets being in the positions of authority within the SSPX, and I'm certain that they're in there.
And it's extraordinarily naive to think that they wouldn't excommunicate the SSPX if they're controlled. That would serve as a deterrent at the very least to prevent more people from going to SSPX, and their going to SSPX and the Tridentine Mass and rediscovering Tradition would not be a good thing for the destroyers.
I'm just stunned at how naive this post is.
Illuminati / Masons / Communists worked for centuries on infiltratign the Catholic Church, and infiltrating the SSPX would be utter childsplay for them. It was well known that if you're bright and could speak 3 languages, you'd rocket to the top very quickly in SSPX, and then they only need a couple of them in there to start appointing more of their own.
Let's say that Bishop Fellay was somehow copromised and under Krah's control. If that were the case, +Fellay was Superior General of SSPX from 1994 to 2018, for nearly a quarter century. That's a lot of time for him to transform the SSPX.
