“I must say, extreme justice is an extreme injury: For we ought not to approve of those terrible laws that make the smallest offences capital, nor of that opinion of the Stoics that makes all crimes equal; as if there were no difference to be made between the killing a man and the taking his purse, between which, if we examine things impartially, there is no likeness nor proportion. God has commanded us not to kill, and shall we kill so easily for a little money?”

1960s, Letter from a Birmingham Jail (1963)
Context: But though I was initially disappointed at being categorized as an extremist, as I continued to think about the matter I gradually gained a measure of satisfaction from the label. Was not Jesus an extremist for love: "Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you." Was not Amos an extremist for justice: "Let justice roll down like waters and righteousness like an ever flowing stream." Was not Paul an extremist for the Christian gospel: "I bear in my body the marks of the Lord Jesus." Was not Martin Luther an extremist: "Here I stand; I cannot do otherwise, so help me God." And John Bunyan: "I will stay in jail to the end of my days before I make a butchery of my conscience." And Abraham Lincoln: "This nation cannot survive half slave and half free." And Thomas Jefferson: "We hold these truths to be self evident, that all men are created equal..." So the question is not whether we will be extremists, but what kind of extremists we will be. Will we be extremists for hate or for love? Will we be extremists for the preservation of injustice or for the extension of justice? In that dramatic scene on Calvary's hill three men were crucified. We must never forget that all three were crucified for the same crime — the crime of extremism. Two were extremists for immorality, and thus fell below their environment. The other, Jesus Christ, was an extremist for love, truth and goodness, and thereby rose above his environment. Perhaps the South, the nation and the world are in dire need of creative extremists.

As quoted in Best Little Stories from Virginia‎ (2003) by C. Brian Kelly, p. 74
Context: What shall we do now? the big knife is coming on us and we shall all be killed. Now we must fight or we are done. Then let us kill all our women and children and go fight until we die? I shall go and make peace!

A Plea for Captain John Brown (1859)
Context: I do not wish to kill nor to be killed, but I can foresee circumstances in which both these things would be by me unavoidable. We preserve the so-called peace of our community by deeds of petty violence every day. Look at the policeman's billy and handcuffs! Look at the jail! Look at the gallows! Look at the chaplain of the regiment! We are hoping only to live safely on the outskirts of this provisional army. So we defend ourselves and our hen-roosts, and maintain slavery. I know that the mass of my countrymen think that the only righteous use that can be made of Sharp's rifles and revolvers is to fight duels with them, when we are insulted by other nations, or to hunt Indians, or shoot fugitive slaves with them, or the like. I think that for once the Sharp's rifles and the revolvers were employed in a righteous cause. The tools were in the hands of one who could use them.
