The Dimond Brothers canard is so tiring. The pitifully small number of Dimond fans among sedevacantists pale in comparison to the numbers of R&R folk touting a Freemasonic, Communist, sodomy defending pope who just happens to have no authority to bind anyone's conscience--pretty much the same view of the papacy as your average Protestant--since they can merely sift his teachings and discard anything they find "objectionable"...but at least they have a pope!
We don't "tout" the current Modernist Pope. We simply do what Catholics have always done - accept that there is a head of the Catholic Church. We've had Modernist Popes at the helm for awhile now. The Catholic Church is occupied by a Modernist sect.
Sedeism, on the other hand, offers a Church without a current pope. Of course this will be appealing to prots who never could stand the idea of a Pope.
