When you're having an argument, there are two different views involved, and maybe two different realities. Instead of making it a black and white, right or wrong argument, try to ask genuine questions to help you understand what the other person is thinking.

Calm down, create mental space, and have a pleasant and relaxing disagreement, after you take the time to listen to the other person's point of view, instead of reacting impulsively or angrily.

Other people may have blind spots and one way to make them understand what you understand is to say to them, ‘So, As I understand, what you are saying is essentially this’ and summarize their position to them.

If your argument hasn’t yet gone in the irrational territory, this will work to have clarity regarding the core matter.

You cannot win a persistent argument while being in that fight due to heightened emotions and a high chance of stepping in a verbal minefield. Better to discuss it later when you are in a different setting, like a dinner date, talking in a relaxed manner so as to not start any new argument.

Having productive arguments is hard, but it is always good to keep trying.
