How people's disaster preparedness is viewed depends on three things:
- are the disasters being prepared for plausible or not?
- do they give off the impression that they're somehow looking forward to the disaster, either as vindication or the opportunity to deem people "looters" and murder them without repercussion?
- is this a form of preparation that theoretically everyone could do, or is there an implication that, in the manner of Jehova's Witnesses, only a subset of the population can be saved?
So, if someone in Florida is preparing for hurricanes by securing their property, moving valuables out of the basement, and preparing for the possibility of evacuation? That's a plausible disaster with no talk of violence, and almost everyone could attempt, so that's a "normal" activity and won't get someone deemed the bad kind of prepper.
