You're correct Johny, a civil war would be bloody and horrific. From my web travels, there seems to be dreaming from both the progressives and the right wing extremists. Dodging IED's while going to work or the grocery store wouldn't be much fun. Or how about losing a child to a sniper. Or hearing about an explosion near your child's school, and worrying if they were injured. Many of the progressives are located in urban areas, and on paper, supposedly these urban enclaves could be choked off so no food or energy enters the areas. In reality it would be a cluster, look at Sarajevo, that was a nightmare for so many.
Unfortunately, I don't see how society is going to deal with the progressives, who have become so militant. They can't be trusted, nor can they be satiated, as they always want more. The current generation of Americans haven't had to directly face war, and I doubt most of them have encountered the squalor and rigors of third world nations. They're too busy with X-boxes and following their sports teams. It is time for the next generation to grow a pair, and protect the few freedoms we still enjoy.
Sorry to sound so pessimistic.
