What is the main conflict in Bearing the Cross by David Garrow?

David Garrow paints one of the most comprehensive portraits of renowned activist and clergyman Martin Luther King Jr. and his championship of the African American civil rights during the 1950s and 1960s. Utilizing hundreds of interviews and F.B.I. transcripts, Garrow delivers an unprecedented biographical look at not only Martin Luther King Jr. as a man but his undertaking of nonviolently forcing an integration of a racially segregated and divided America.
