One outcome of tragedy is that it further polarizes existing opposites. Everyone retreats to their respective corner. We use the tragedy to reinforce our stereotypes and justify our worldview. By this, we are driven further apart.
In the last 30 days we've had multiple national tragedies. Orlando, Baton Rouge, St. Paul, and Dallas are a few. We have retreated to poles such as:
Christian vs. Muslim
Pride vs. Anti-gay
Trump vs. #nevertrump
Black vs. White
