When we discuss politics we often discuss it as if political views were a straight line from right to left (or left to right), and that everyone has a place on that line. In such an analogy the ends of that line are as far apart from each other as one could imagine. Therefore, when a series of tragic, politically motivated, shootings strikes our country in the way it has these past couple of weeks, those toward one side of the line or the other either try to blame the other side, keep score, or minimize their own role in promoting the extremism of their own side.
