If the argument is rigged for you to lose, the only winning move is to walk off the court.

Some disagreements are not attempts to reach an understanding, they are structures where every answer you give becomes further evidence against you. Playing on by rules designed to produce one outcome does not get you a fair result, it only prolongs the loss and wears you out. Recognising the shape of it is most of the skill.

Notice when explaining yourself is making things worse instead of better. Say one clear sentence and stop. Leaving is not a concession about who was right, it is a refusal to keep paying for a verdict already written.
