"They" do no such thing, but like St Athanasius, (which is back to the original point made by Narses) they do point out when churchmen teach heresies.
I have even been told that it is a heresy to call John Paul "the Great."
Really by whom? It certainly isn't a heresy to hold that opinion, but when John Paul II's papacy is compared to the papacy of the other popes given that title it does appear to be an uniformed opinion to say the least.
Actually, the SSPXers (with apologies to St. Pius) who attend the local chapel, Our Lady of Fatima, insist that the Church teaches heresies. As do my family members in St. Mary Kansas and Post Falls, Idaho. They insist that the Catechism is filled with heresies as well as the GIRM, for starters. I have no idea how this reconciles with Christ's promise that the gates of Hell will not prevail against the Church. But they say it, over and over and over again.

* Pope Benedict, at lesst twice publicly, has referred to him as "John Paul the Great."
But, compared to your personal opinion, what is Pope Benedict informed about?
