When it comes to contentious issues, we rarely have genuine conversations regarding them. Most “conversations” are just opportunities for each person to express their own point of view. Neither person does much listening to the other, and neither expects to learn anything from the exchange. Their only goal is to declare their point of view, and perhaps convince the other person in the process.
This is not a good approach. We should come to every conversion believing that the other person has something to offer. We should be listening, not just making points. After all, we could be wrong in what we believe, wrong about particular facts, etc. Our “opponent” may actually have insights that we could benefit from, so we should be open and ready to be corrected if necessary.
