"Groping for some middle ground between the right and the wrong"

On the anniversary of Lincoln's birth, from "Abraham Lincoln's Cooper Union Address" (February, 1860). Lincoln is responding to those who threaten to destroy the Union over the question of slavery. His argument, it seems to me, has relevance to certain current issues:

.... But you will not abide the election of a Republican president! In that supposed event, you say, you will destroy the Union; and then, you say, the great crime of having destroyed it will be upon us! That is cool. A highwayman holds a pistol to my ear, and mutters through his teeth, "Stand and deliver, or I shall kill you, and then you will be a murderer!"

To be sure, what the robber demanded of me — my money — was my own; and I had a clear right to keep it; but it was no more my own than my vote is my own; and the threat of death to me, to extort my money, and the threat of destruction to the Union, to extort my vote, can scarcely be distinguished in principle. ....

[W]hat will convince them? This, and this only: cease to call slavery wrong, and join them in calling it right. And this must be done thoroughly — done in acts as well as in words. Silence will not be tolerated — we must place ourselves avowedly with them. Senator Douglas' new sedition law must be enacted and enforced, suppressing all declarations that slavery is wrong, whether made in politics, in presses, in pulpits, or in private. We must arrest and return their fugitive slaves with greedy pleasure. We must pull down our Free State constitutions. The whole atmosphere must be disinfected from all taint of opposition to slavery, before they will cease to believe that all their troubles proceed from us.

I am quite aware they do not state their case precisely in this way. Most of them would probably say to us, "Let us alone, do nothing to us, and say what you please about slavery." But we do let them alone — have never disturbed them — so that, after all, it is what we say, which dissatisfies them. They will continue to accuse us of doing, until we cease saying.

I am also aware they have not, as yet, in terms, demanded the overthrow of our Free-State Constitutions. Yet those Constitutions declare the wrong of slavery, with more solemn emphasis, than do all other sayings against it; and when all these other sayings shall have been silenced, the overthrow of these Constitutions will be demanded, and nothing be left to resist the demand. It is nothing to the contrary, that they do not demand the whole of this just now. Demanding what they do, and for the reason they do, they can voluntarily stop nowhere short of this consummation. Holding, as they do, that slavery is morally right, and socially elevating, they cannot cease to demand a full national recognition of it, as a legal right, and a social blessing. ....

Neither let us be slandered from our duty by false accusations against us, nor frightened from it by menaces of destruction to the Government nor of dungeons to ourselves. LET US HAVE FAITH THAT RIGHT MAKES MIGHT, AND IN THAT FAITH, LET US, TO THE END, DARE TO DO OUR DUTY AS WE UNDERSTAND IT.
