Trying to win a comment war is like trying to wrestle fog. You’ll get tired and it’ll still be there.

There is no position to be taken in that kind of exchange, because nobody involved is there to be persuaded. Each reply supplies material for the next, and the argument grows in proportion to your effort. You will end the night depleted and the thread will look much the same.

Decide before you type whether this person could change your mind, and assume the answer runs both ways. If not, close it, and let the last word belong to someone who wanted it more. Save the energy for conversations where someone might actually be listening.
