That is true. And those revivals lead to the south being called the Bible Belt. Of course there are other factors which lead to the southern religious movement post-war such as the poverty. But in southern cities until recently you could not walk a block without finding a church of some sort and in the rural areas it is still very much that way.

Now I am not saying that these observations were the total cause and reason for the northern and southern cultures to have developed as differently as they did along regional boundries. But one of the reasons that people came to America in the first place was to excape religious persecutions in Europe. This is why the Quakers and the Pilgrims came according to conventional history. It is not unreasonable that the religious beliefs of those peoples, which were different from the common European religious beliefs of Catholicism, Anglican, or Calvanist, shaped the culture of their region. This is the only reason I can determine of why the two religious viewpoint on the subject of the morality of slavery existed. Why to one religious group it was acceptable and another it was abhorant.

And as I said this attitude "religious rightness or wrongness" colors our discussion of the whole Civil War to this day.
