I can't say what you believe, but we do know for a fact that the men who formed the Confederate States of America did not believe those words from the Declaration above. Read the Cornerstone Speech to see Stephens actually criticize Jefferson, et. al. for penning those ‘foolish’ words and expressing the notion of equality. The Confederacy was founded on the bedrock principle of inequality. It made no bones about it.
It had no moral case.
I agree. However, I am trying to debunk the notion that the right to secession can be based upon the law of the government. If so, then there is nor "right" to self-government at all.
