Some people are getting pretty defensive. Let me point out that the article is not about you. It's not about stocking food for a few weeks. It's about, as the title says, people who prepare for the collapse of civilization. The good thing about ETS is that it's not a survivalist forum.
Furthermore, I didn't see anything in the article that could be construed as an attack on survivalists. It just seems to try to report on the phenomenon, and attempts to make sense of it historically and socially.
