But there's something else worth highlighting, and the speech above is a really good example. It's the end of "We Shall Overcome," an incredibly powerful few minutes. Almost lost in the applause, you can hear King giving the rapturous crowd instructions.
He's telling them to attend a meeting. After the heights of this speech, it seems an absolutely mundane thing to do. "That's why we're fighting for a more moral universe against all odds. Meet me in the fellowship hall in 10 minutes." Not a call to find themselves, not pulling them towards vague evolution, King wanted a concrete, immediate action. The rhetoric's important, but it's that combination that made the civil rights movement work.
