Well, the label used to be “survivalist” and that had a bad connotation, so the word, “prepper” came along. Pick any other word and it will also become a bad label because it represents the same thing, us.
The commie lady bureaucrat at the link (Valerie Hyphen-Somebody)decided to make the distinction between “prepper” and “doomer”. A Doomer was selfish, and not interested in the community-at-large, only his own selfish hide. So the new term of derision is Doomer.
Probably true, and the best you can hope for is to stay one step ahead of the MSM that despises “preppers”.
One idea might be to copyright and trademark a name, that can be used only under limited circumstances. The open source movement has put a lot of thought into this. Imagine the glee of demanding royalties any time the MSM used that name.
Ive just accepted the term hoarder. It now has such a negative conotation that people think i only have junk and garbage.
