"Among free men,” said Abraham Lincoln, “there can be no successful appeal from the ballot to the bullet; and those who take such appeal are sure to lose their cause and pay the costs.”
Yet we seemingly tolerate a rising level of violence that ignores our common humanity and our claims to civilization alike. We calmly accept newspaper reports of civilian slaughter in far off lands. We glorify killing on movie and television screens and call it entertainment. We make it easy for men of all shades of sanity to acquire weapons and ammunition they desire.
Too often we honor swagger and bluster and the wielders of force; too often we excuse those who are willing to build their own lives on the shattered dreams of others. Some Americans who preach nonviolence abroad fail to practice it here at home. Some who accuse others of inciting riots have by their own conduct invited them.
Some looks for scapegoats, others look for conspiracies, but this much is clear; violence breeds violence, repression brings retaliation, and only a cleaning of our whole society can remove this sickness from our soul.
For there is another kind of violence, slower but just as deadly, destructive as the shot or the bomb in the night. This is the violence of institutions; indifference and inaction and slow decay. This is the violence that afflicts the poor, that poisons relations between men because their skin has different colors. This is a slow destruction of a child by hunger, and schools without books and homes without heat in the winter.
This is the breaking of a man’s spirit by denying him the chance to stand as a father and as a man among other men. And this too afflicts us all. I have not come here to propose a set of specific remedies nor is there a single set. For a broad and adequate outline we known what must be done. “When you teach a man to hate and fear his brother, when you teach that he is a lesser man because of his color or his beliefs or the policies he pursues, when you teach that those who differ from you threaten your freedom or your job or your family, then you also learn to confront others not as fellow citizens but as enemies – to be met not with cooperation but with conquest, to be subjugated and mastered.
