That's exactly right, Matthew, and I sniffed him out in my first response: "But, then, perhaps you're Salza again with a different account [claiming] that the Conciliar Church has not erred."
This was a troll job. Using the ostensibly motive of attacking sedevacantists, he was working up R&R folks against sedevacantists, hoping to mobilize them against sedevacantism, whereas he was actually attacking all Traditional Catholics, and hoping to fly under the radar, getting R&R and SV to battle against each other, and then, after the bodies had fallen where they did, he would execute the R&R folks who remained standing by turning on them. It's the old divide and conquer tactic, where you get your enemies to fight each other, and after both sides are decimated, you mop up what's left.
I didn't see R&R attacked by this Random Fish guy. But now that he's banned (which is a good idea, even though he was right about a few things), we can now get back to certain sedevacantists who attack R&R traditionalism. Obviously, it's not a problem that sedevacantists are anti-R&R trad here.
Trads here are very much divided even without the additional presence of someone like Salza.
