Good points from all. A short story-
I once had a friend (soldier buddy) who went to many of the same mobilizations and countries that I did. He had commented on the food, women, houses, clothes behavior of the people from all the places he visited stating America is so much better in all areas. He made very critical judgements, often stating facts. I mentioned he was exeriencing “ethnocentrism” and it was common for soldiers to do this when traveling abroad. I found over the years he was not interested in being introspective or learning much from others. He was sure about everything he knew about himself and the greater, bigger world around him. I often think about him when I read some comments made by audiophiles. We all can grow and learn, if we want to. If we see the education in that process and the benefit it can provide.
