I wish something like the sunrise movement started a new religion about taking climate change seriously. No sky bully, just people gathering weekly to hear about the earth, what we can do to make it better.
What would the core tenements be?
I’ve also thought about this a bit and this is my best pitch. But I don’t think it’s very likely to happen when it’s hard enough just getting by for most people now.
In a very similar situation to you 4 years ago and we eventually just went with a community Facebook page because it’s what most people are already on and use. I hate it. Not a good answer but even discord was too niche. Only 59 homes in my community though. You may have more luck with larger groups.
Also, community building has mostly been a flop. That stuff is hard.
