Those arguments are usually posted out of ignorance of history and, in a lot of cases, a hatred of Southerners.
I have no hatred for southerners, I am one, but let’s study the issue truthfully, the confederacy was created by democrats in order that they would not have to debate or vote on slavery in the halls of congress.
Too many southron scholars see Lincoln’s brilliant tactic of offering a permanence to slavery to the south as sign he was willing to allow it to be formally legalized in the United States Constitution, he wasn’t so inclined. He wanted a debate and a vote knowing that in Congress the forces of slavery would surely lose, they knew it too and so the confederacy was born to escape the debate over slavery.
I fully agree.
