To me, in my observation, it boils down, ultimately, to education. We're taught a certain way for a certain reason. Even in college we're taught just the tip of the iceberg. As one college professor of mine pointed out - it is our responsibility to discover the rest of the submerged iceberg floating in the icy waters. Self-education, as well as continuous education is paramount to being as well-informed as possible. For many though, they have not the time nor inclination to pursue educational activities once they graduated high school or left college. They rely on, all too often, what they've learned in school, or perhaps what they hear on TV or from friends and coworkers as the foundation and makeup of how they perceive the world around them. These are the people operating on the tip of iceberg. And all too often, when those types of people are exposed to the submerged part of the iceberg, in my observation, there are two responses: 1) they recoil from it in various ways or 2) they have a desire to know more. The former is the more common of the responses I've personally seen, either in person or online.
