Nothing is more punk than food not bombs. It’s just feeding everyone who shows up whether the government likes it or not.

Yes, and, Food Not Bombs is a great example to bring up, because they don't only feed everyone, they also share literature and talk politics and organize community action. From FNB's how to guide:

Your meal is not a Food Not Bombs meal if you don't provide literature and display a banner. Otherwise the public will think you are a church and have the impression your group believes that our political and economic system is fine and that all we need to do is care for those who are not able to make it. We are not a charity, we are seeking to build a movemnet to end the exploitation of the economic and political system.

I think very few orgs do "the personal is political" better than FNB.
