That is not what happens. Instead, we unconsciously blame those that are least apt to defend themselves. We attack the hungry, the poor, the illiterate, the homeless, the uneducated, the powerless and the disenfranchised. It becomes familiar habit. We learn that dialogue intent on producing mutually acceptable solutions to problems is a sissy activity.
Civility is boring.
We are taught that compromise is akin to giving in. Over and over we expose ourselves to the message - Respect is power. Power is respect. Strength comes from dissing, silencing, demeaning, degrading and humiliating an opponent. It is the one for whom voices do not cry out loudly.
