Hi, interesting perspective, but I would like point out that Lincoln never outlawed slavery. The Emancipation Proclamation of 1863 freed all persons held as slaves in the states which had seceded from the Union. So, slaves in border states, like Maryland, and slaves in Southern territories already held by the North at the time (like North Carolina) were not freed by Lincoln. They remained slaves until the end of the Civil War in 1865 or so when the North won and the 13th Amendment was rattified.

But, this did not end all slavery in America, only chattel slavery, as the 13th amendment explicity permits penal slavery.
