I read an interesting paper a few years ago that informs how I look at this stuff on some level. One of the authors is kinda sus and the movement is overall pretty white and merits some criticism for sure, but I think the basic approach could be helpful. Basically it argues that we should collectively presuppose that societal collapse is inevitable because policy will not respond adequately to climate change. If that were true then we ought to be forming community networks and building infrastructure and skills to be prepared to preserve the things that are most important, since in a triage situation like this you won't be able to preserve everything. I think resiliency is a useful attribute for any organization to have, and necessarily requires reaching out to people around you in order to collect relevant skills and just raw manpower for what will need to be done.

Granted I am working nights and am doing an abysmal job of learning to garden and shit, but I when I have time to think about proactive steps these things are where my mind goes. I guess you could see it as a type of vanguardism? The idea is to be creating conditions where your group is organized enough to step up when the opportunity presents itself. Maybe that's still defeatist I don't know.

Sorry, it's a bit rambly.
