@tinker Thank you for this great post! I found my mutual aid group (a food not bombs style cooking group) over a signal chain message I got from a demo drumming group I was in at that time, which in turn I found at a demo when I danced to their music.
We cook (nearly) every Sunday for about 3 years now and bring the food to a place where many unhoused people hang out. We get our food half from dumpster diving, half we just buy it. For a time we got much food from a community farm, but at one point it was just too much work unfortunately. The money for buying food we get from donations when we cook for political events that align with how we want to build the world.
One of the biggest challenges is to close the gap between people who mostly cook and people who mostly eat. I don't mean that everyone who eats should cook, but the mostly cooking people and the mostly eating people are still mostly separate communities and one of them holds most of the power, which is a charity-like power dynamic. It is a slow process and it's starting to get better, but it's a lot of hard work to destroy those boundaries. We are now moving into a new, hopefully more accessible space.
