No sane person wants a civil war.
You ask a question I might have answered differently when I was a younger man.
Now, I fear that the "civil war" will be driven by desperation created by a collapsing economy and a climate that is becoming less and less habitable with each passing year. I have pulled back from the world a bit, and am fortunate to have a readily defendable and self-sufficient place to hunker down and let the conflagration burn around me.
In the end, the only people that are in danger of being shot by me are those who might bring murderous hostility against me and mine in an extreme breakdown of social order. I hope we don't ever get close to such a situation, but I see the warning signs on the horizon.
