/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.
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.
