I've been involved in a dialogue with Nanette from the Progressive Focus Center
in the comments section of an earlier post of mine. We've been chatting about how to craft a message that would inspire culturally disparate elements of the Left to show up for each other's battles. I like this concise statement/question with which she concludes one of her entries:
". . . if we combine people power, standing up for one another, effective change (poverty, homelessness, lives, etc), ownership of the process by the people, racial, social and economic justice, sustainable existence (does environment fall under that?), and anything I missed, what concept/theme/narrative do we wind up with?"
