We can declare the pope excommunicates himself when he says the adulterated mass. Pope Pius XII made it clear to the world, any clergy who supports state and gov't in 1940's, was excommunicated for they followed the Marxists ways. And Pope Pius XII also said, if the laity align themselves with these excommunicated clergy, they too are excommunicating themselves.
I do believe that is where the majority of traditional catholics agree.
Traditional catholics do believe that the way Christ set up the Church with a head, is where it is to be. We are not like protestants who believe in no pope.
As long as any clergy aligns themselves with Marxism, New Order mass, they are publicly showing they are against Christ and his Church.
