nice
Just a couple thoughts here (and I don't claim to be an expert, but I deal daily with large numbers of people of differing backgrounds, social levels, moral levels, etc,):
Buster, good on you for trying to put forward this idea. It has its merits, but as I'm sure you've seen here, preppers are naturally suspicious of other people's motives- and rightly enough so. I've often thought that not enough people have the foresight to have any kind of plan/gear in the event of SHTF or large natural disaster/war/what-have-you, and of those, many only think of themselves as an isolated island. Others want to be part of a community, a collective. Most recognize that in a worst-case scenario, prepping is not just about survival of the family group or individual- it could very well mean survival of the race/culture.
Any group of people, especially a group of individuals, needs to take into consideration compatibility. In every aspect. For a group to function, there has to be; a) a purpose to banding together; b) some kind of understanding of 'general rules' for the group as a whole- the Golden Rule? The Ten Commandments? It doesn't have to be organized, but there has to be something; c) SOMEONE has to swing the gavel and be able to make decisions for the group. I am not speaking of governance, but of survival. Someone must, in some fashion, be the de facto 'leader' or spokesperson for the group. In a survival scenario, there will be times when decisions, IMPORTANT decisions, LIFE AND DEATH decisions, will need to be made, and followed WITHOUT HESITATION. There is no time for a democracy when the wolves are at the gate, and chewing on the walls. Discussion can occur only when the crisis is past.
This is one thing that I see spoken of very little, and discussed even less. For a group to function, there has to be some kind of structure, like it or not. If it's a pack of outlaws you want, ruled by whomever is fastest with their weapon of choice, or a commune of vegans, many of the societal norms we take for granted will be null and void. You may find yourself judge, jury and executioner, final arbiter of all matters. What kind of behaviour will the group tolerate? Encourage? Shun? Marital groups - monogamy, polygamy, polyamory? The devil is in the details, as they say, and without sounding smug and tramping on other people's beliefs, my personal opinion is that if SHTF in the worst-case scenarios, God (whatever God you prescribe to) is likely sitting this one out and probably doesn't get to have an opinion.
Might be more than 2 cents there, but there you have it. Best of wishes in your endeavours.
