As a retrospection of America's tumultuous antebellum era, About All That Disdain for the Old South avails its reader truly disturbing revelations.  It affirms that 1860 presidential candidate Abraham Lincoln well knew the Old South's slaveholders to be completely secure in their constitutional authority to practice slavery:  and therefore further understood that secession, if undertaken, would in fact be an act intended by Southerners as the remedy for a grievance unrelated to any threat of abolition.  Revealed are the reasons why Republicans declined to dignify the Old South's real grievance and why, as a consequence, America forfeited the potential to avert the Southern secessions by means of a quid-pro-quo implementing a repeal of the U. S. protective tariff reciprocated by an emancipation of the Old South's slaves.  Further disclosed is the fact that Lincoln himself publicly cited, from his own research into the nation's birth, information with which secession can be proven a lawful act.  In short, this essay discredits everything you think you know about the reasons why the Civil War occurred in America.
