There is information on what a “Devils Advocate” is online.
I don’t mind people being critical but without any suggestions it doesn’t really do me any good.
Someone can say that a plane my fall on my head, but it isn’t very useful unless they suggest an alternative, even if it is going into a cave and never coming out again.
I offered thoughts on what might be needs for shelter and even pointed out what I thought were flaws in a backup generator scenario with an alternative suggestion.
Be all that as it may, hopefully we will both survive if society does break down.
Luck to you in your endeavors.
