Why and how did the south defend slavery after 1831?

Well before 1830 the south defended slavery just out of pure necessary evil. However, after 1831 their ideology changed and they began to defend slavery as  "positive good." They blindly argued that slaves were in a good condition and were happy, content and well cared for. Moreover, they made up all sorts of things saying slavery was better then being an actual worker.

explanation:

as the old saying goes, all politics are local. state and federal governments affect our daily lives in numerous ways. yet, in our federal system, there is supposed to be a balance between federal and state power. as james madison envisioned it in federalist no. 51, “the power surrendered by the people” would be “divided between two distinct governments,” creating a balance of power that would enable the “different governments [to] control each other.”
