But then the Cotton Gin kicked in and so did the money. Since they were no longer soul-searching about ending slavery they now had to justify why they had human chattel. Biblical sources were used, mudsilers spoke, and a host of other justifications invoked to justify slavery, even if they tried to avoid using that term. When those justifications failed (and oh, did they fail) they could always resort to the likes of Preston Brooks to keep them nasty Northerners out of their peculiar institution.
