Is perhaps the least popular position for a person to hold, despite that it is the correct position.

Those who argue that "Things are not as simple as all that" or whatever, really are only obfuscating the truth.

If a 'pope' has heresy, he cannot be the pope.  This is a TRUTH that must be assented to and recognized, since it flows from the dogma that heretics are outside the Church.  To argue that a notoriously heretical man is somehow not a heretic without a trial is to wait for the "crooks to police themselves", as many have stated.

No, Catholics must judge the objective offenses against God in the external and denounce those who commit the violations until they prove their innocence, by abjuration and profession of Catholic Faith.

And this necessarily means that they must hold all the dogmas of the Holy Church, not as opinions about them may have developed over time in the minds and writings of fallible men, but as they were declared by the Solemn Magisterium of the Church, whereby the MIND OF GOD AND OF THE CHURCH ON THE MATTER IS DEFINITIVELY KNOWN, which in itself is a dogma.

Those who fail to adopt this unpopular position generally, as far as I can gather, have too much at stake in their image, career, social circles, etc. to want to make the leap of Faith, and put respect of persons before respect of God.
