We disagree with the precepts for the Southern Revolution. Once the North started advocating for overthrow of southern society via Harper’s Ferry, war became inevitable. Even a constitutional amendment guaranteeing slavery in perpetuity could not stop it.
I’m not sure your analogy works. Harpers Ferry was lawfully suppressed. Most law abiding citizens of the US were against the Revolutionary violence of John Brown. Similar to the “hands up don’t shoot” madness. The Republicans strongly denied any association with the man and his Revolution. Lincoln campaigned for no slavery in new territories only.
