The original Rand [Ayn Rand] for whom Rand Paul was named had the maxim: it is always wrong to initiate violence, and it is equally wrong to let violence go unanswered. She did not have "being annoyed" in mind for what the answer should be.
minor point, but Rand was not named after mother of Libertarianism Ayn Rand. His name is Randall. RP has said so himself. Although it was a convenient coincidence.
