I find that people who have racist beliefs often see differing viewpoints as the enemy - the first breach being simple consideration of a new perspective. True, but the problem is not limited to racists. I'm in the "moderate" part of the political spectrum, and I find that far too many people on both the left and right have the same behaviors. I suggest to my left-leaning friends that government should be a "last resort" solution at best, and is frequently actually the problem; to my right-leaning friends I explain the crucial importance of privacy, civil liberties, and equal justice; and in either case the response is frequently incredulous disbelief and contempt for my naivete and/or obvious privilege yada yada yada. The echo chambers are real, and they are a threat to our civil society.
