King concluded moral appeal to white conscience alone could not defeat entrenched racism

Evidence

In the short time between his bout with depression in Grenada and his murder in Memphis, Dr. King came to understand the depths of American racism. He had underestimated how deeply rooted white supremacy was in the habits of American life. How the transformation of the heart he had so eloquently preached about since the 1955 Montgomery bus boycott required a fundamental change in the practices and structures of the country—change that could not depend solely on the moral conscience of white people, no matter black people’s willingness to sacrifice and suffer, because of their investment in white supremacy. In fact, in August of 1967, King stated plainly, “The vast majority of white Americans are racists, either consciously or unconsciously.” — Eddie S. Glaude Jr., Democracy in Black, 269
