Question: What should we do when we are confronted with other cultures?

This answer to the question above does not only sticks to the book, but also can come from our real life. What have I done when I first when to the school in the States? How did I handle such different culture? How did I manage to get along with the foreigners just fine when I was in a culture I have never experienced? The answer is simple: I have treated them with respect and with familiarity, regardless of my conceptions of them and regardless of their prejudices of my ethnicity or my nation.
It is same of every culture. The answer to the question is very simple. We should not give importance to their culture when we confront other people. Before recognizing them from their culture, we must acknowledge them as breathing, living people, just like us. It is then when we appreciate their culture.
The second step can be considerably hard. We have to understand their culture. This can be challenging according to how unique the culture is. In the case of Don Richardson and the Sawi, this would have been very difficult. Since we have acknowledged them as human beings, we need to give our full respect to them. However, at the same time, we need to appreciate their culture, no matter how inhumane and brutal their culture is.
Once we have recognized them as human and fully understood them as human, and their culture no longer stands in our way to do so, no more problem lies between the two cultures. We can fully appreciate them and so can they. All it takes for two cultures to become friendly are some respect and pure understanding.
