There are people everywhere who cuss preppers (even some on this board). Just think if the rapture comes before tribulation starts, we are actually prepping for those left behind. I'm thinking people who say they will kill us for our supplies, likely aren't Christians, so they are left and they get all our supplies for free.
In that case, I'll take the rapture and they can have my supplies as I won't need them again. Therefore, non Christians should pray for the rapture - no, wait, they don't pray, oh, well.....
The reason that I’ve gathered as to why most leftists hate preppers is that we are escaping the judgement of their own eschatology.
Their highest form of nirvana seems to be that everyone suffers, that “we’ll all be in the same boat” as one put it. This is their equivalent of the “new heavens and earth” promised to Christians in the Bible.
They, for some reason, think that condition to be FAR SUPERIOR to the present state of affairs where some people, through their own hard work and choices, live better lives than others, and don’t have to beg for sustenance.
Preppers, by being prepared to have a sustainable life outside the collective and not dependent on the “god” of government, are screwing up their perfect world.
