Commenting on the battle between Ares and Athena in Book 21 of the Odyssey, scholar Silvia Milanezi offers some sound advice:
. . . when Zeus gives permission for the god to choose their favourites, Ares challenges Athena to single combat provoking her by such harsh words as . . . ‘dog fleas’ . . . . Athena quickly silences Ares’ insults: she knocks him out, hitting him with a stone, and finishes him off with her laughter and insults (21.408). He who dares call her a dog flea (421) is quickly reduced to dust.
Emphasis added. Let that serve as reminder to you all.
