Yeah, but if you haven’t noticed about every gun manufacturer is moving out of the Blue States.
Actually, it was going quite well until Lincoln issued an executive order to acquire many thousands of inspired and motivated combatants for the blue side to replace the thousands upon thousands of blue deserters.
You're right though, the outcome was never really in question and to this day the South has never recovered from the utter destruction of their economy but especially, - the culture - and I'm not talking about a slave owning culture.
Never in the history of US armed conflict did the United States wipe out completely an enemy culture - the Germans, Japanese, - culture not only survived but flourished - Islam? - we currently celebrate all that is Islam. Why, we even have a muslim chief executive.
Tell me I haven't lived long enough.
