Not I. Bocca Della Verit was one of the few intelligent persons on this board.
Really? What makes you think so?

Big Mouth was the author of a blog that used to attack all kinds of different clergy, mostly sedevacantist. It's not at all clear that he was a sedevacantist himself, though, as he never espoused any theological position, but would always claim that any clergy that operated outside the structures of Rome were illegitimate. This would include everyone to the right of the Indult groups, I suppose. But mainly his blog was devoted to pointing out misprints and minor errors in newsletters of traditionalist bishops such as Bp. Sanborn and Bp. Dolan, and complaining about various petty faults of different trad priests, and similar childish stories.
He claimed that he had a whole staff of people writing on his blog, and that they belonged to all different persuasions in the trad world, but the style was always the style of one man. After nearly a decade of operation, he started talking about how he was going to start a movement of his own, -- the details were extremely vague -- involving validly ordained traditional bishops from the new church or something like that, I don't even remember. Finally, in 2018 he said he was going to take two weeks off writing the blog to get this new trad congregation (or whatever it was supposed to be) started, and it was going to be the greatest thing ever in the trad world. That was the last post ever posted on that blog, so it's been defunct for three years now.
His religion seemed to be attacking others while never espousing a position of his own. I am glad to see him gone.
