Stepping in with what might seem like a glib response, I'd like to say that the various racial minorities I spend time with are doing pretty much the same kind of thing as the racial majorities... It's not the action, it's the communication. If this were a political movement and there were organizers trying to build momentum and clout and voice, we'd be building coalitions of folks with like-minded interests. As is, forums like these and other areas of the world are images of the societies in which they exist.
Stated differently: there's plenty of poly-like behavior across all of society, and it's a question of finding the conversations and figuring out the different definitions and vocabularies.
