If Pope Pius XII declared in 1940's that clergy were supporting the state/gov't and he said they were excommunicated. And those who are told not to follow them, do follow them, are also excommunicated.
If all those who followed Pope Pius XII, were invalidly nominated, that is, the lineage continued to be Marxist, then what do you call the people who can not follow or be as Pope Pius XXII stated, excommunication? We can do that to ourselves. These popes after Pope Pius XII are manifest in their actions. A pope must be Catholic.
