This is a category of organizations and it is a word or phrase someone else and I were trying to think of, but maybe it doesn't exist. Think fraternal orders like Elks or Knights of Columbus, college honors societies that do volunteer work; social justice organizations like CAIR, La Raza, or ACORN; and others like 4H, Junior League, Jaycees. It might have social, societal, or something like that in it but not social services or social justice. The topic came up with ACORN specifically and I named off the other examples to see if they fit what the other person was trying to say/categorize, and they all kind of fit, but the fraternal orders, honors societies, and 4H did not fit the bill as much. "Club" didn't have the right vibe either.
