I still don't know what you're trying to say here. Do you think that all slave-holding states had a strong belief in individual liberty? Saudi Arabia is a good counter-example, not much tradition of writing tracts about the virtues of greek democracy there. No, the princelings sure jump when the big man says jump.
When people say that the Cavaliers were into individual liberty, they aren't saying the blindingly obvious fact that non-slaves generally preferred not to be enslaved.
