Unless you can provide evidence for this by quoting a damning passage from the article, I'll have to regard this as one of those psychological tricks I used to play on my classmates ("I'll bet you are not brave enough to eat that disgusting worm!").
Sure, simply look at the first example the writer gave. It's a woman who has "a large generator, portable heaters, water tanks, and a two-year supply of freeze-dried food that her sister recently gave her as a birthday present."
That's the writer's opening example for his overall point. Apparently, there is nothing else "unusual" to say about the woman. That's it. Meanwhile, the writer puts this woman in the third person category of "they" or "them", meaning a broad category of people who prepare for a large-scale disaster. The writer is literally putting himself on the other side of the fence.
My initial reaction to that example was the woman sounds like me, just with more stuff. I only have about 6 months of toilet paper (LOL). You may be uncomfortable being considered one of "them". I, on the other hand, am not.
