Let us apply a few tests. You say that you think slavery is wrong, but you denounce all attempts to restrain it. Is there anything else that you think wrong, that you are not willing to deal with as a wrong? Why are you so careful, so tender of this one wrong and no other? You will not let us do a single thing as if it were wrong; there is no place where you will allow it to be even wrong; there is no place where you will allow it even to be called wrong! We must not call it wrong in politics because that is bringing religion into politics; we must not call it wrong in the pulpit because that is bringing politics into religion…and there is no single place, according to you, where this wrong thing can be properly called wrong!
-From Lincoln’s March 6, 1860 speech at New Haven
