I grew up in the 1980s in Texas, watching stuff on TV like the The Day After and Damnation Alley and lots of other bad post-apocalyptic sci-fi schlock. Meanwhile, my parents took us to a church that was very focused on Christian eschatology*, so my childhood daydreams revolved around on how I would survive in the inevitable supernatural, post-armageddon war zone. I used to imagine how buildings would look when they were all burned out and destroyed and possibly occupied by mutants.
I’m sure that’s why I’m so into growing vegetables now. I’ll be ready with my basement full of turnips when the shit goes down.
One of my college professors argued that Christianity at its heart is a religion about redemption in the afterlife, and if the ancient Jews weren’t so miserable under the Romans, the religion never would have caught on. Even today, it appeals to people most often that are at the end of their rope.
I suspect a similar dynamic applies with all these doomsday preachers. People like talking about the end of the world because these scenarios offer them hope out of whatever mess they’re stuck in currently. For example, as a delinquent 7th grade kid, I knew that if we went to war with the Russians, or if a meteor crashed into the Earth, or if a super-virus plague broke out, or if aliens landed and started harvesting our life force, I wouldn’t get in trouble for not doing my world history homework, so on some level, I wanted it to happen.
[*] has very little in common with Christian scatology. It’s just a pretentious word that means what the religion believes will happen at the end of the world.
