For the record, that's as fine as any other hobby, as far as I'm concerned. Just as I don't have any issues with... you know, survivalism as a hobby.

On the aggregate, though, there IS a bit of a prepper power fantasy at play, I stand by that. Hey, I have tons of hobbies myself where I find the collective average lands in a super creepy place. If anything I think it's a relief to acknowledge it. Gives you plausible deniability.
