If you’re losing the argument, change the question, not the volume.

Losing on one question and getting louder about it only loses more conspicuously. Often the question itself is the problem, because somebody framed it in a way your position cannot win, and the honest move is to say so. Shifting from whether you broke a rule to whether the rule makes sense is legitimate when it is true. It becomes a dodge only when the first question deserved an answer.

When you notice yourself repeating the same point harder, stop and ask what is really being decided. Name the better question out loud. If the original one was fair, concede it cleanly.
