I think that there are a lot of FReepers wishing for the same thing, who don't comprehend this either.
The last Civil War depopulated the country by somewhere between 2 and 5 percent. That was without modern weaponry, and a population that was a whole lot more self-sufficient. I'd shudder to think of what modern warfare would look like, on the same scale. 2-5 percent casualties would overwhelm our (already troubled) medical system, and frankly, I think that would just be a warm-up.
There comes a time when violence is necessary and inevitable, however, CW II is an event that I look forward to with trepidation, not enthusiasm.
Less like 1861 than like 1776, I think. The feds, some law enforcement some military and some politicians playing the role of the King's oppressors. Some libs playing the part of the Tory informers, very few volunteering for armed service for the regime, others hiding and trying to stay out of the line of fire. As for our side, no George Washington, but a bunch of quality lower level leaders. A lot of us holed up in a defensive posture and setting occasional ambushes; a few of us actively hunting the enemy leadership.
I agree with your take; not a pleasant thought or a cause for celebration.
