I thought about writing some disagreement with the author, but as they have stopped arguing with people it would be pointless. /s

Instead I will simply say that an argument is /not/ about winners and loses, it's about communicating ideas and reaching consensus. The moment you bring your own ego into the argument, you've become the loser because you destroyed any opportunity to reach consensus, invalidating the entire point of sharing your thoughts or listening to others. If you aren't prepared to listen, understand, and reach consensus, why are you involved in the conversation at all, you're just wasting your time and the time of others and damaging relationships.

I am unsurprised that that author found themselves in multiple situations where they lost the room despite "proving themselves right". Humans are not computers, conversations are not programs, and they don't have deterministic outcomes based on the inputs. It matters how you conduct yourself, and it matters if you are trying to truly understand other people or just talking past them. An audience is never going to be swayed if you act like an asshole, even if you think you are right.

One of the most important things I had to learn in my life when I was younger was the value of listening and empathy, and how it deepens our own intellection. Logic and empathy are not opposing concepts, although it is often trendy to think so now. Logic requires empathy, reason requires empathy, because what are you reasoning about except for systems which interact with humans?
