There's no evidence whatsoever for any of his wild speculations in which he assaults Traditional Catholicism as a whole and the SSPX in particular.
There's no evidence that the explanation is any more deep and profound that Bishop Fellay and one or two other superiors were so protective of the "reputation" of the SSPX that they either covered up the tracks of one or two of these priests or else caused them to be dismissive of the allegations. Perhaps there was a certain cognitive dissonance at work, where they were themselves so reluctant to believe that those who appeared outwardly to be devout and dedicated Traditional priests could be guilty of such things. In fact, amidst the scant evidence actually offered by CM, some written communication and recorded conversations, this does in fact appear to be the case, with +Fellay making comments about how the victims were damaging the Society, and one or two other priests dismissing the allegations as lacking in credibility. And that of course is bad enough, and I am not minimizing the gravity of having done this.
Could it be worse than that? Sadly, yes. But there is absolutely zero evidence that it is, and the rest of Dr. Lamont's speculations are entirely without merit. He is taking on the aspect of an armchair pop psychologist. But if that were all there was too it, I wouldn't spend any time with it.
There are some allegations and insinuations here that border on slander and calumny. In fact, if he does not provide evidence for what he asserts, he has in fact committed grave calumny.
