If we choose only to expose ourselves to opinions and viewpoints that are in line to our own, we become more polarized, more set in our own ways. It will only reinforce and deepen the political divides in our country. But if we choose to actively seek out information that challenges our assumptions and beliefs, perhaps we can begin to understand where the people who disagree with us are coming from.
Before we get too depressed about the state of our politics, let's remember our history. The great debates of the past, all stirred great passions. They all made somebody angry, and at least once led to a terrible war. What is amazing, is that despite all the conflict, our experiment in democracy has worked better than any form of government on earth.
