Yes, wasn't Arius a crypto-Jew?
But what's this to do with sedevacantism?
Sedevacantism is schism. The Jews in the Protocols admit to promoting schism. The Dimond Brothers have Jєωιѕн last names and promote schism. They've been at it for years and have dedicated their entire lives to it. They aren't total idiots, as proven by their research, so they know (at least by now) sedevacantism is a bogus theory, so they must be encouraging the lie on purpose while knowing it's a lie.
The only people sufficiently motivated to do something like this are the Jews.
The Dimond Brothers' use of insulting propaganda (e.g. unfortunate photos of past popes) demonstrates skill. The Jews are the masters of propaganda and insult by their own admission:
Protocol 17... insult, the faculty of employment which is so well known to our race.
It's impossible to avoid the conclusion that the Dimond Brothers are Jews.
