It's interesting how understanding something to resolve a problem, as opposed to perpetuating it. Many times, when we see or hear someone saying or doing something unusual, our first reaction is to make judgments about something we really don't understand. If what we observe doesn't conform to what we learned from past experiences, we promptly dismiss it.
Even if we may disagree with a person's point of view or don't understand one's behavior, we may pre-judge the rationality of their view or behavior without understanding that there may be legitimate reasons why a person believes or behaves the way they do. Whether these reasons are good or not is a matter of interpretation. The fact is, with every observable act, there's always a genealogy of events that have pre-conditioned any moment that confronts us.
