Obviously you do not, nor do you seem to care much for historical accuracy.
You have to remember WHY Marx "supported" Lincoln was that he wanted a communist revolution and his theory (WRONG) was that such revolutions would occur in CAPITALIST countries. This alone tells you that even the father of communism knew the South was not "capitalist," but feudal.
Obviously you are unfamiliar with Marx's writings on the war then, as he clearly identified Lincoln as having ushered in the new stage of workers revolution IN the south.
