You mean they wanted to exercise their Constitutional states right to own slaves. That is what the Confederacy was all about. All this Lew Rockwell, Ludwig von Mises, Rockford Institute, League of the South, Lincoln bashing bs is all about defending racist attitudes and is an attempt to spread Neo Confederate propaganda. Deny the N. Bedford Forest was the head of the KKK. Soon we will be told the KKK was a fine civic organization like the PTA that was trying to protect little children. It is just like the Holocaust denial that Neo Nazis try to spin.
No, you don't have to be a historian to write a book about history, but it is impossible to have creditability if you write that Lincoln was a criminal.
