You can win the argument and lose the friend. Decide beforehand which one you actually care about.

Being right and keeping someone are separate outcomes, and pursuing one hard enough can spend the other. In the middle of it they feel identical, because winning seems like it will settle everything, when what it usually settles is who is now careful around whom. Some arguments are worth that cost. The difficulty is deciding while your blood is up.

Ask, before you begin, which one you would keep if you could only have one. Put it to yourself in those words. If the answer is the friendship, you can still disagree, just more slowly and with fewer of your best lines.
