Please learn some history.
You have primary sources available to you. In the Southern newspapers of the day, and in the secessionist speeches you will find all the material you need to discover that a specific "right" was being defended by the South. And it is a "right" which no state had, has, or ever will, legitimately possess.
“Please learn some history. And it is a “right” which no state had, has, or ever will, legitimately possess.”
Says, you, you arrogant idiot. We do know history. You know your opinion as history. That’s arrogance and ignorance.
Idiots like you project 21st century values on 19th century people. In the 19th century slavery was legal and the “normal” state of things. Blacks were considered inferior of intellect, like children. Every one was a racist INCLUDING LINCOLN. Abolitionists were considered terrorists!
