I don't think doomerism or anti-natalism are serious positions, but I will not have leftist prepping lumped in with them! The imperial core is collapsing and that's going to be really hard to live through without at least some knowledge about canning, solar panels, gardening, rainwater collection, repair, and how to shoot a gun.
What distinguishes lefty prepping from the normal rightist variants is a focus on building community before it's too late, and that's literally how we'll build a future. In fact, prepping on the left comes from a belief that there is a future, it's just going to be hard (not even forever, just long enough that the power might go out).
Prepping is literally working for tomorrow, like???
