JUST PAY YOUR TAXES, EVERYTHING WILL BE FINE…
Secession does not necessitate war; nor was war necessary to end slavery. The rest of the world (including all of the Northern states) ended slavery peacefully in the nineteenth century.
No respectable historian would argue that Lincoln invaded the South to free the slaves. Even his Emancipation Proclamation was only a "war measure" that would have become defunct if the war ended the next day – and it was written so as to avoid freeing any slaves since it only applied to "rebel territory." Both Lincoln and Congress announced publicly that their purpose was not to disturb slavery but to "save the union," a union that they actually destroyed philosophically by destroying its voluntary nature, as established by the founders. All states, North and South, became wards or appendages of the central government in the post-1865 era.
What Lincoln did state is. . . if Southern secession made it impossible for Washington, D.C. to "collect the duties and imposts" (i.e., tariffs on imports, which had just been more than doubled two days earlier), then there will be an invasion. He followed through with this threat, and that is why there was a war that ended up killing 750,000 Americans, in addition to some 50,000 Southern civilians, while maiming for life more than a million; Say very clearly about war in his first inaugural address was that it was his duty "to collect the duties and imposts," but "beyond that there will no be any invasion of any state.
