A talmid chacham is called a talmid for a reason- we all need to keep learning and keep growing. Just because one has reached a high, virtually unassailable condition doesn’t mean that one is now beyond reproach.
This whole situation reminds me of when I heard a speech from a kiruv professional who said something displaying a real and total lack of derech eretz. I walked out. If he’s supposed to be telling me why I should be frum, and he’s frum, and he’s acting this way- it doesn’t add up. I don’t see why I should be learning my most profound hashkafos from someone like this. I’m not on the level yet of Rabbi Meir, who could eat the pomegranate and throw away the peel.
