EXOD734 Maimonides (sic) (Nachmanides commentary to this verse) reminds us that the Torah forbids Jews to curse a sitting Nasi, or king. Even if the person who holds the title is deplorable and miserable at his job (a moral sinner), this person may still not be cursed due to his current position. Cursing a man is equivalent to cursing the office, and respect for the office must be retained, no matter who has the post. But once the Nasi is removed, no such prohibition exists.
