King documented a white bishop joining the Meredith March despite black activists’ exclusionary wishes.

Evidence

Marian shared a passage that King wrote about her father in his book Where Do We Go from Here: Chaos or Community? In it, King discusses the importance of white people working in the civil rights movement: “During the Meredith March in Mississippi, when some of the young activists were saying, ‘We don’t want whites,’ Bishop Moore of the Episcopal Church said to Walter Fauntroy of the Washington Southern Christian Leadership Conference
’That march is protesting a moral evil, an evil detrimental to me and every American. I’m going down there.’ ” Marian, Susanna, and Paul were raised understanding that enslavement was wrong for all parties, white and Black, and that both were impacted by the violent institution. — Tamara Lanier, From These Roots, 881
