It should be noted that the civil rights movement and the Black Power movement were not mutually exclusive. Many would argue that the two are just aspects of the larger Black Liberation movement. For example, there were many members both Black and White members within CORE who started off in the civil rights aspect of CORE but stayed with CORE as it went Black Power. Below is an attempt to clarify how these two aspects of CORE differed in terms of philosophy and tactics.
Most of the members who came in during the 1950's and 1960's like Norm and Velma Hill or Marv and Evie Rich, were not. To them, nonviolent direct action was a tactic, a technique to be used in protests, the only one that would work under such circumstances being in America.
CORE being specifically an interracial group was seen as significant due to the power of the image of both Black and White members working together. Houser saw it as the counter argument to those who would claim: Blacks were the ones causing problems by protesting; Blacks and Whites could not live much less work together.
Many, perhaps rightly so, do not see CORE today as the 'real' CORE. One member went so far as to say that national director Roy Innis simply hijacked the name. Many believe that CORE really ended
Even though many of the older members would disagree, CORE was still a viable organization and doing a lot of good. Up until 1968, there were still Whites (although very few) in the national office and some chapters.
According to then national director Floyd McKissick, the six points of Black Power in CORE were:
"Black power is not Black supremacy, Black violence and Black hatred for the White man." The overwhelming emphasis was on putting Black people in political office, putting Black and Latino people into positions of power in the public school system and putting Black and Latino studies in the curriculum.
When it came to politics, CORE was framing its demands very much in the American tradition - "an ethnic group banding together to engage in bloc voting and bloc competition". It emphasized organizing blacks into a Black power group similar to how American Italians, Jews, Irish, etc. had in order to achieve these goals.
It should be noted that not all members who went Black Power would be considered Black nationalists, such as Harlem CORE's Joe Jackson. The difference between the two, which was a thin line, has much to do with the nationalists' concentration on separatism and culture. The Nation of Islam, for example, was not a Black Power organization in that it did not participate in partisan politics and had its own schools.
There were also different forms of Black nationalism. There was the more conservative nationalism advocated by leaders like McKissick, Roy Innis and Long Island CORE's Mel Jackson which focused more on economic power for liberation. Members like Brooklyn CORE's Jitu Weusi advocated a more cultural nationalism that focused on education and culture as the keys to Black liberation, especially for children. Others like Sonny Carson of Brooklyn CORE identified themselves as revolutionary nationalists. Similar to the Black Panther Party (BPP), he advocated socialism and the overthrow of the United States government which was seen as fundamentally corrupt. While the BPP was a Black power organization, it did not advocate nationalism. Carson, however, was a member of both simultaneously. Again, it was sometimes a thin line.
Ironically, it was the White members in many ways who started CORE down this path in their conscious decision to have Black leaders of both the local chapters and national organization.
There were also some White members who felt the same as the Black members in that the cause of freedom was not moving fast enough. They formed what can be seen as White alternatives to 'CORE as Black Power' with groups such as the Weathermen (which included Eleanor Stein of Brooklyn SCORE and David Gilbert of Columbia University CORE) which advocated armed resistance.
Then there is the curious case of the American Committee on Africa (ACOA), which in many ways was a spin off of CORE. ACOA supported Black Power overseas even though it was made up primarily of members from CORE who were against Black Power within CORE and in some ways how Black nationalism manifested in the United States.
