Having stated that, we can safely agree a faithful catholic can indeed "discuss" the Pope's actions without malice.
With respect to discipline, there is precedence that JP2 has put the foot down when he wanted to, for instance, in the case of firing the "Condom bishop -- Jacques Gaillot of France" in 1995.
As far as that missing phrase "with due reverence ...." in Canon 212, it is irrelevant in light of the substance of the discussion. Besides, the authors did not display disrepect or malice towards the Holy Father. The article is a fair and honest critical analysis of the "content" of his speech.
No. He says the Pope is useless (just read the article, please).
I see nothing wrong with the Pope, I say the author is useless, and the publication that printed his heretical diatribe is useless.
