This topic is a recurring one, especially for the original poster.
In this year's version, the original poster posited that the approaching band was a church group.
Ok. I will give you an example of what happens in the REAL WORLD.
http://news.yahoo.com/escape-from-n...-key-bridge-to-fleeing-residents-215830472.ht.
A group of volunteer workers who stayed behind in Katrina, had to evacuate. This wasn't 35 days into shtf or even a week.
They were turned away at gun point at an escape bridge. It wasn't "racist": as the sole ***** councilman had also voted to close the bridge.
It wasn't like there was a desperation for food or for looting.
I know that we have ferverent religious people out here. In the real world, unless it is just that religious (let's give everything away) guy in charge of a small group, the situation will parallel this real world scenario in Katrina.
FYI, when scenarios are posted like this one, survival skills include transposition (the ability to see the world from the other guy's perspective) and situational awareness. If a person truly believes that a scenario is as simple as two forces standing out in the open in formation with muskets aimed at the other side like in the Disney film Johnny Tremaine, he is going to die.
Another example. Korean War. Movies or real world newsreels. A mass of refugees coming down a road to a checkpoint. Sometimes NK infiltrators. Sometimes refugees forced along at gunpoint. Checkpoint people say stop. In fact sometimes there are no infiltrators. What happens? The refugee column is attacked. This is real world, and it doesn't matter that you have been religious or a conscientious objector your whole life.
If, in this year's hypothetical, you are deliberately static, in the real world you are going to fight or have to run away. It takes some real leadership (thinking) to have figured out how to interview people, keep the useful ones, and integrate them into the existing group. Most people do not have those skills and will not have them when shtf.
