Hi Gary,
"The group’s members are drywallers and flooring contractors, nurses and painters and high school students. They stockpile supplies, practice survival skills and “basic infantry” tactics, learn how to treat combat injuries, study the Constitution and train with their concealed handguns and combat-style rifles."

Kind of a broad brush there don't you think?  I would also add that many of these folks are of the same make-up that moved from Europe to the east coat, westward, and north to Alaska the last couple of centuries.
