I don't think it matters anymore which occasions or bishops are more or less dangerous. There is a clear pattern that in the spirit of conciliar good will and collaboration, the SSPX will invite or allow or host conciliar churchmen any chance they get. Anyone who disagrees with this approach will be branded as bad willed and mean, "uncharitable" and an obstruction to the alleged mass conversion of souls that is about to happen through the SSPX's most holy condescension.
