Do you know your reasoning behind why Jefferson wrote about the wall of separation is also the reasoning used by others to explain the 2nd Amendment? So that Southerners could create armed militias to track down runaway slaves and put down slave rebellions?
Who do you think owned slaves in the South? Buddhists?
Christians owned slaves in the South. And they used the Bible you are so proud of to justify that ownership.
Why do you think Southern Baptists and Southern Methodists and Southern offshoots of other denominations formed? So that those denominations could provide a theological foundation to support slavery.
