The principle, on which the war was waged by the North, was simply this: That men may rightfully be compelled to submit to, and support, a government that they do not want; and that resistance, on their part, makes them traitors and criminals. No principle, that is possible to be named, can be more self-evidently false than this; or more self-evidently fatal to all political freedom. Yet it triumphed in the field, and is now assumed to be established. If it really be established, the number of slaves, instead of having been diminished by the war, has been greatly increased; for a man, thus subjected to a government that he does not want, is a slave. And there is no difference, in principle -— but only in degree -— between political and chattel slavery. The former, no less than the latter, denies a man’s ownership of himself and the products of his labor; and asserts that other men may own him, and dispose of him and his property, for their uses, and at their pleasure. – Lysander Spooner
The south used that principle of coercion to accept government that people didn’t want, forcing bad government on black slaves, and denying that Northern states could ban slavery within their boundary. The principle of the US government is rule of law, whether you want it or not. True, most criminals and traitors will protest that they do not want law that condemns them, but there are legal remedies to bad law, such as petition, pardon, appeal, and election. The southern rebellion was made to overthrow law, for the sake of the institution of human slavery
The war was started by Southern treasonous scum who wanted to create ‘’a great slaveholding Confederacy, stretching its arms over a territory larger than any power in Europe possesses’’- South Carolina governor Francis Pickens.
