Traditionalist Catholics, like children or mental patients, are often rather perspicacious in their judgments of others (and this is not always a bad thing!).
However, it is not okay to trash talk the or a Pope. It is in poor taste and bad judgment to bash popes, living or deceased. If this is your problem then get smart and change. If you can't, then pray for the grace. Bitch all you want, but not about the popes.
As Job told one of his counselors: "If you and I were to change places, I could talk like you" (Job 16:4).
