I must say I felt like putting my finger down the back of my throat with Cassman's final statement, which was sanctimonious nonsense, claiming that we must stay in the NO because we must fight the battle and not bail out like cowards, etc.  This has nothing to do with this whatsoever.  We're bailing out because it's NOT THE CATHOLIC CHURCH, and not due to fleeing from cowardice and refusing to suffer with the Church.  That was utterly obnoxious.  From Revelation/Apocalypse 18:4 "Go out from her, my people; that you be not partakers of her sins, and that you receive not of her plagues."

Cassman actually came of as more of a meanie than Bro. Dimond. 

A reply to an earlier comment about being Benedictine.
There's a vast difference between being a member of a community with an actual professed monk from an actual canonical monastery where he was formed who left because of the changes and he guides you through the way of life, having a bishop take your vows publicly.
And having a postulant without vows and no formation trying to form you.
Big difference between all traditional religious orders ( the former ) and the latter ( Diamonds). They were even offered to be formed by benedictines and sent back to their monastery after vows. They refused.

That's interesting to know though, do you have a source for the last point? It still doesn't change the fact that he and his apostolate does great work to defend Catholic doctrine.

The Founder of our Benedictine community:
Brother Joseph Natale O.S.B.
Brother Joseph Natale was trained at St. Vincent’s benedictine Arch-abbey in Latrobe, PA. St. Vincent’s Arch-abbey was the largest Benedictine monastery in the United States. In the 1960’s, Bro. Joseph left with the permission of the then Archabbot Dennis Strittmatter to start his own Benedictine community. Shortly after leaving St. Vincent’s, Bro. Joseph started his Benedictine community in southern New Jersey. Bro. Joseph never allowed the New Mass to be celebrated at his monastery, only allowing the traditional Roman Rite Mass. Bro. Joseph printed, distributed and sold numerous books, pamphlets and audio tapes defending the Catholic faith and educating Catholics about the true teachings of Catholicism. In 1994, the community was given a piece of land in rural New York. Bro. Joseph wrote and stated on many occasions that he would be moving the community to New York. But Bro. Joseph was not able to complete this desire, due to the fact that he died on November 11, 1995. After Bro. Joseph died, Bro. Michael Dimond, O.S.B. was elected superior of the community. Bro. Michael immediately went to work to fulfill Bro. Joseph’s wish to move the community to New York. In late 1997, Most Holy Family Monastery finally finished moving the community and its belongings to New York.
Bro. Michael Dimond O.S.B.
Raised in a family with no religion, Bro. Michael Dimond converted to Catholicism at the age of 15. Brother Michael Dimond entered Most Holy Family Monastery in 1992 at the age of 19, a short time after graduating from high school. Brother Michael Dimond’s father graduated from Princeton University in New Jersey and his mother graduated from Stanford University in California. Brother Michael Dimond was elected superior of Most Holy Family Monastery in late 1995. Bro. Dimond took his final vows before a validly ordained priest.

According to Michael Cuneo (p. 88), who cites the archivist at St Vincent's, Br Joseph Natale was only a postulant (briefly) and never took final vows. You can watch an interview of Br Joseph . Please note that they sing Roman Compline (as opposed to the monastic form) in English.

He was a postulant and not even a novice. The whole point of the offer was to give them a monastic formation, this offer was made to the entire community by the Benedictine priest who did the funeral. There was no brother anything as none took vows, all were some varied form of postulant/novice.

 So postulants voted another postulant as superior? They did this after being given a chance at formation and then gave themselves vows?
There's more but that should suffice.
They're not benedictines. They may have non Benedictine vows though

You claim that there are "important differeces" between sedeimpoundism/Chazalism and sedeprivationism.  Since it's so obvious to you, please do explain.  I have not yet seen a single convincing distinction between the two that would dissuade me from my contention that the two are identical.  More than anything it's a matter of emphasis.  Some of the leading proponents of sedeprivationism today are also some of the most dogmatic formerly-sedevacantist, and so their emphasis is on the formal vacancy, the lack of authority ... to the point that it may sound like sedevacatism, where with Father Chazal, his emphasis is on the material possession of the office.  So when they speak, they might SOUND like dogmatic SV vs. R&R, but in theory, the positions amount to the same thing:  possession of the office but with lack of any actual authority.
