Yes, this is the kind of stupidity to expect from someone who's malicious and has zero intelletual honesty.
+Lefebvre "line" priests condemn +Lefebvre "line" priests all the time, starting with The Nine vs. Lefebvre, and then one SV after another, and then FSSP types that condemned +Lefebvre for the consecrations, and the myriad +Lefebvre "line" priests that went back to the Novus Ordo, and then the +Lefebvre line priests of The Resistance condemn the +Lefebvre line priests of the neo-SSPX
... and now
Resistance priests Pfeiffer, Hewko, et al. condemn Bishop Williamson and the other Resitance priests
Then Hewko leave Pfeiffer and condemns him
Fr. Ringrose, Resistance priest went SV
Pfeiffer of the Resistance went +Thuc-Palmar line
So if any group fragmented in LITERALLY RECORD TIME, where you had priests condemning one another ... that was the Resistance.
I can't believe that Scuмmage attempted to try this tactic, as if it wouldn't blow back in his face, where he was trying to throw a bucket of manure right into an industrial sized fan. Only someone who's been stultified by malice wouldn't see what was about to happen. So furious with rage, he hurls the contents of the bucket, and the rage makes him oblivious to the fan.
I recall when Fr. Chazal put out his little chart of the SV groups in trying to attack the SVs, and I said at the time that he'd better be careful about trying that tactice ... and within weeks you had Pfeiffer insulting Bishop Williamson outside his door at Broadstairs.
