Everybody already knows Voris's bias. He plainly states the SSPX is in schism. His personal opinion on the canonical status of the SSPX does not change his reporting of the facts.
Unfortunately, too much of his video wasn't facts, but, rather, layers of crap into which he sprinkled facts ... in service of his bias (a bias which you here admit).
And it's not at all unlikely that Voris too engaged in various activities that would have put him in handcuffs. This guy has little humility given his own sordid past. Bishop Sheen used to say on visits to prisons that "the only difference between you and me is that you got caught." It's quite possible that the only difference between Voris and those he's attacking is that they got caught and exposed. It's one thing to expose facts, which should certainly be done, but quite another to present them with such a haughty and cocky attitude. If I had committed adultery, for instance, and then later caught someone doing the same, I could rebuke him in charity, but it would be the height of hypocrisy to look down my nose at him and call him a scuм for what he did. I'd be in no position to do so, and Voris is in no position to cop his attitude either. Unfortunately, he did a great disservice to the objective of rooting out abusers by doing what he did.
