Yes, a baseless accusation that Lincoln was going to force change through legislation, which was asinine as it would have required a Constitutional amendment to get rid of. Thus a political cause for getting rid of it.The CSA was founded on NO CHANGE, the CSA was founded on the a baseless accusation that Lincoln was going to get did of slavery when he became president.
Economically, they would have been forced to get rid of it eventually, which is what I mean by "natural death" of slavery. If there is no money in it, there is no point in doing it, and why I was talking about them Industrializing when the North "couldn't" do it before. With actual need for the goods, there would be people that would do it, particularly if there is money in it, which there would be.
By quick, I mean a war that is over in a year or two, which admittedly would require the "Stupid Virus" to hit McClellan and other General's harder than it did OTL. And Britain/France recognizing the CSA.
