Being polite and having good manners is important, but if someone is rude to you, you certainly don't owe them any courtesies. If someone pushes your buttons, then let them have it. Celebrate your obnoxious side today and use your creativity to craft an insult that will really get your point across. You aren't someone who can sit quietly while someone disrespects you or a loved one, so why act like you are? Conveying truth in you actions is never a mistake.
