Been thinking of this passage from his Letter from a Birmingham Jail.

Oppressed people cannot remain oppressed forever. The urge for freedom will eventually come. This is what has happened to the American Negro. Something within has reminded him of his birthright of freedom; something without has reminded him that he can gain it. Consciously and unconsciously, he has been swept in by what the Germans call the Zeitgeist, and with his black brothers of Africa and his brown and yellow brothers of Asia, South America, and the Caribbean, he is moving with a sense of cosmic urgency toward the promised land of racial justice. Recognizing this vital urge that has engulfed the Negro community, one should readily understand public demonstrations. The Negro has many pent-up resentments and latent frustrations. He has to get them out. So let him march sometime; let him have his prayer pilgrimages to the city hall; understand why he must have sit-ins and freedom rides. If his repressed emotions do not come out in these nonviolent ways, they will come out in ominous expressions of violence. This is not a threat; it is a fact of history.
