/r/collapse is very fertile ground for agitation, more so every year. This new subreddit, specific to the global supply chain collapses, is also a place where we can speak directly to the emotions people are feeling and the material conditions creating them. If it isn't full of socialists it will soon become full of libertarian preppers.
edit: I've also got no part in leadership there. It started popping up in crossposts yesterday.
Doomerism is still viable energy to work with. Sure we probably won't win a revolution that staves off climate change in time, but the alternatives are worse and the one viable option for trying will at least hurt the people responsible for climate change while giving that person's family less suffering even when conditions worsen. The shades of doom between that person's children having opportunities despite climate change and being denied opportunities to further insulate the rich from climate change are very broad. Without an attempt it's the kind of doom a stray dog faces when it's put on a kill list. Nobody will come to help, there's nothing they can do, and the benefits of it dying will never be felt by it. You're still speaking to things that fit into that Kubler-Ross model for the grief they're experiencing.
I agree with everything you said and said things like it myself over there. Responses were 100% negative.
I've had better luck with liberal vegan subs.
