After half reading these last few pages it's pretty clear why strict "libertarians" don't get elected, and when they do they don't hold any powerful positions (ie Paul).
With respect to the Civil War, to classify it as "good guys vs bad guys" would be beyond simplistic. I'm not defending anyone who supported racism, but at the same time imagine if you lived in a southern state and your family was threatened like that. You'd fight to protect your land and family. Many people did that, and payed the price. I'm not going to call every confederate soldier "bad."
