Some of CORE's main leadership had strong disagreements with the Deacons for Defense and Justice over the Deacons' public threat to racist Southerners that they would use armed self-defense to protect CORE workers from racist organizations, such as the Ku Klux Klan, in Louisiana during the 1960s. Others, however, strongly supported the organization. By the mid-1960s, Farmer tried to incorporate elements of the emerging black nationalist sentiments within CORE—sentiments that, among other things, would quickly lead to an embrace of Black Power. Farmer failed to reconcile these tensions, and he resigned in 1966, but he backed his replacement, Floyd McKissick.
