I certainly avoid people who speak too loudly. The foundation of politeness is to not make other people uncomfortable. I think there’s an important difference between someone like Asimov who did know that what he did was wrong, but might not have understood the gravity of it, and someone like Biden who (presumably) just behaved in a way that was natural to him.
