A Lot of the Lunatic fringe just can't make it in society and want The Stuff To Hit The Fan because they think that by having a few supplies, and some guns, they can be "Important" or "a Leader" or "People will quit making fun of them (maybe even do some bowing and scraping)" if Society will just hurry up and collapse... Folks, That's Lunacy!! If you have to hope for the system to be torn down to below your level before you feel good about yourself.. you need a little professional help.. And (again, As I have said for Years) "Powerful people are powerful by nature".. if you put them in a disaster, or on a desert Island with 20 people, they will Still gain power... they will gain power in Any environment... it's simply in their nature... the setting is incidental, whether we consider these people good or bad.
The Guy that can't get the respect he feels he deserves Right Now, is not going to get that respect After TSHTF either. That's a proven fact... History, and countless disasters, proves this out time after time.
Sadly, There are a lot of these people that Want to see society torn down so that They can be "better off" finally. They feel "cheated" in life, they feel like someone is holding them back (someone is.. *themselves*!)
