Conversations are almost never about proving a point; they are about exchanging ideas (however controversial or disagreeing they may be), contemplating nad debating the ideas, and drawing insights from that. A disagreement can always be expressed softly.

Personally, I learn, reflect, and gain a lot from engaging in conversations with other people, as – not infrequently – the others complement my understanding of points I might have previously not considered or missed. I call it knowledge, and knowledge is power.
