By our readiness to allow arms to be purchased at will and fired at whim… we have created an atmosphere in which violence and hatred have become popular pastimes.
Martin Luther King, Jr.
 
We challenge the culture of violence when we ourselves act in the certainty that violence is no longer acceptable, that it's tired and outdated no matter how many cling to it in the stubborn belief that it still works and that it's still valid.
Gerard Vanderhaar
 
Much violence is based on the illusion that life is a property to be defended and not to be shared.
Henri Nouwen
 
The cause of violence is not ignorance. It is self-interest. Only reverence can restrain violence - reverence for human life and the environment.
William Sloane Coffin
 
There will be no justice as long as man will stand with a knife or with a gun and destroy those who are weaker than he is.
Isaac Bashevis Singer
 
We have cracked down on library books, cell phone calls, fertilizer purchases, and wearing shoes in the airport, but we have done almost nothing at the state level to make it harder for either a terrorist, garden variety armed robber, or young person to get their hands on a handgun.
Sarah Brady
 
I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent.
Mahatma Gandhi
