Rabbi Yitzchak Adlerstein has just published a fascinating essay, "Who Deserves to be Our Hero?" in which he argues that if we seize upon every error in order to disqualify a rabbinic leader, there will be no more Torah heroes left: "Heroes need not be perfect. Gedolim need not be perfect. They never were, and they never will be. A person who demands never to find fault in his or her mentor will never have a meaningful mentor."
