Step-by-step explanation:
The main point of "To Those Who Keep Slaves, and Approve the Practice" is a) Abolition of slavery. This document, and others like it from the period, sought to promote the moral argument against slavery and envision a United States where individuals of all races could exist on equal footing.
During the antebellum era, the growing political movement to address the issue of slavery intensified the divides within the nation, with northern abolitionists pushing for emancipation and an end to the institution of slavery, while southern slaveholders fought to protect what they saw as their property rights and a key part of their social and economic system.
Abolitionists used moral suasion to persuade the public of the immorality of slavery. They envisioned a society where formerly enslaved Black people would have equal standing with White people. Conversely, southerners defended slavery, arguing that it was a positive economic and social institution that benefited not only the economy but also the enslaved by exposing them to Christianity and civilization.
