No, I'm afraid that you don't see the point. The Southerners had such a low opinion of the fighting capabilities of the Yankees that they felt that their secession would be an easy fight and a foregone conclusion.
The North thought that they had the manpower and the equipment to easily subdue the rebellion and that poor Southerners would not fight for the blueblood aristocracy.
Both were wrong ... and, if Generals Lee, Longstreet, and Johnston had been different people, the Confederate Army would have taken to the hills to fight for years in a guerilla war against the occupying North.
Again, I would give you the warning ... things rarely turn out as expected.
But YOU don't see the point. Liberals have little capacity for combat or military discipline. That's why the miltiary ranks are so overwhelmingly conservative (and from the south and mountain west, for that matter). The North had a cause (the preservation of the territoral integrity of the United States). How the heck are the liberals going to fight when they don't even let their boys play with toy guns. And what cause are they going to lay their lives down for? Gay "marriage"? Keeping Al Franken on the air?
