Interesting points. We've all been on both sides of this issue in different subject matter. Sometimes the person won't come up for air while talking over you. Usually those people are afraid you're going to disagree with them. Sometimes, it seems like people who ask you a question are only interested in receiving an answer that they agree with. Like that guy at the range you mentioned. He didn't seem to be interested in testing his premise to find out if maybe he was wrong. He just wanted you to agree with him and continue shooting with his rifle with loose scope mounts. He didn't even seem to be interested in your observation that his scope mounts were loose. He seemed more interested in being right (according to him at least) than in not wasting his ammo and not getting his rifle sighted in. When we're younger we tend to argue with those people. As we get older, we realize we have less time left on this planet and arguing with somebody like that simply wasted range time or time for doing something else productive. It's helpful though if you don't smile when you agree with them or don't argue as they somehow seem to know they're wrong and tend to get huffy if they think you know they're wrong.
