I refuse to allow myself to sink so low. I will continue to zealously advocate for my clients in my own nice, honest way. I disagree that civility codes are an effort by some to squelch the voice of the different. These concepts do not belong to the rich and privileged. They belong to every person on the planet.
All people deserve to be treated with respect and dignity.
Be civil and professional even when faced with conduct that shocks and stuns. It will wear off on those around you. In the end, legal cases are won or lost on the merits, not on who yells the loudest. And, in case you are curious, my client eventually prevailed and I never raised my voice. That principle allows juries to decide the law as well as the facts.
