So you're one of those annoying people who yells "Bingo" to hear everyone groan, then follows up with "Just kidding"
I cited the Lincoln as an authority on why the North prosecuted the war. Since he was essentially the one prosecuting the war, I assumed he would know. Since both of you are normally defending him, I thought he might be an authority that you'd accept. Perhaps you fell for Non's diversion, but I didn't.
So here, we will try it again for the third time now:
The unionists who prosecuted the war did not give a fig about ending slavery. With this in mind, attempt to generate a coherent (I know, it will be difficult for you) response outlining why Southern Independence had to be stopped. On your marks, get set, GO (x3 now)!
Lincoln prosecuted a war that was thrust upon him. He had little choice other than bow to southern aggression and turn over forts and facilities that belonged to the U.S. It was the Davis regime that turned to war to settle the matter, not the Lincoln Administration. So the question you should be asking was why slavery was worth launching a war over?
...attempt to generate a coherent (I know, it will be difficult for you)...
It appears from reading our posts that coherence is not the problem here. It's comprehension on your part.
