The claim was made that slavery was on its deathbed and would have died out within a very few years without the Civil War. I'm still trying to find out why you people believe that and you all keep throwing out irrelevancies. If you can't answer the question then just say so.
A few years? Nobody said "a few years." It would have taken decades, but again, how much is your life worth? In exchange for the lives of 750,000 men, I think three decades is not unreasonable.
How long did it take in Massachusetts? 150 years?
