Bossy, know-it-all, and super preppers are dangerous to everyone that is part of a group of people trying to help each other survive. Too often preppers tend to undervalue someone who may not fit the mold they are trying to fill. They discount someone not physically as capable without realizing wisdom and common sense gathered over a lifetime can often outweigh and/or supplement their own preps. Often long-term survival requires skills that are quiet, less visible, and more subtle but will keep you comfortable longer. The end goal is re-establishing normalcy in society.
