Part of the problems with race relations in the South today is the failure to reach a common undertstanding of the southern relationship between the blacks and white of that era. Our concepts of that era is these absolutes that the blacks and white were always master and slave like in the old Roman society and did not live and work together in that Southern society. They most certainly did. The Southern society was not that of the Roman Empire.
Did each have their "place" in that society? Yes absolutely they did. One of the best examples that I can think of is that a mistreated slave does not normally accept the religion of a crual master even by force. Why should the slave accept the God, who teaches mistreatment of those who are beneath him.
