One problem is that both sides of this "schism" tends to easily fall into a Cosy Catastrophe mindset [0]. Not always, but it happens quite a bit. They touch on this in the article, but it's too common in my opinion. It's tempting to start daydreaming about an escapist fantasy where you've prepped exactly right and society collapses exactly how you want it or thought it would happen. Maybe it's a world where you can violently defend your homestead against bandits. Maybe it's a world where all your hungry neighbors band together in harmony to protect one another. The truth is a long-term scenario that would require prepping would be chaotic beyond anything you can imagine and yet parts of society would continue on exactly as before.

This is not an article about preppers, it's just another article about Reddit drama.
