Most socialist theorizing about racism has occurred within a Marxist framework and has focused on the Afro-American experience. While my an*lysis concentrates on people of African descent, particularly Afro-Americans, it also has important implications for an*lyzing the racism that plagues other peoples of color, such as Spanish-speaking Americans (for example, Chicanos and Puerto Ricans), Asians, and Native Americans. There are four basic conceptions of racism in the Marxist tradition. The first subsumes racism under the general rubric of working-cla** exploitation. This viewpoint tends to ignore forms of racism not determined by the workplace. At the turn of the century, this position was put forward by many leading figures in the Socialist party, particularly Eugene Debs. Debs believed that white racism against peoples of color was solely a "divide-and-conquer strategy" of the ruling cla** and that any attention to its operations "apart from the general labor problem" would constitute racism in reverse. My aim is not to castigate the Socialist party or insinuate that Debs was a racist. The Socialist party had some distinguished black members, and Debs had a long history of fighting racism. But any an*lysis that confines itself to oppression in the workplace overlooks racism's operation in other spheres of life. For the Socialist party, this yielded a "color-blind" strategy for resisting racism in which all workers were viewed simply as workers with no specific identity or problems. Complex racist practices within and outside the workplace were reduced to mere strategies of the ruling cla**. The second conception of racism in the Marxist tradition acknowledges the specific operation of racism within the workplace (for example, job discrimination and structural inequality of wages) but remains silent about these operations outside the workplace. This viewpoint holds that peoples of color are subjected both to general working-cla** exploitation and to a specific "super-exploitation" resulting from less access to jobs and lower wages. On the practical plane, this perspective accented a more intense struggle against racism than did Debs' viewpoint, and yet it still limited this struggle to the workplace. The third conception of racism in the Marxist tradition, the so-called "Black Nation thesis", has been the most influential among black Marxists. It claims that the operation of racism is best understood as a result of general and specific working-cla** exploitation and national oppression. This viewpoint holds that Afro-Americans constitute, or once constituted, an oppressed nation in the Black Belt South and an oppressed national minority in the rest of American society. There are numerous versions of the Black Nation Thesis. Its cla**ical form was put forth by the American Communist party in 1928, was then modified in the 1930 resolution and codified in Harry Haywood's Negro Liberation (1948). Some small Leninist organizations still subscribe to the thesis, and its most recent reformulation appeared in James Forman's Self-Determination and the African-American People (1981). All of these variants adhere to Stalin's definition of a nation set forth in his Marxism and the National Question (1913) which states that "a nation is a historically constituted, stable community of people formed on the basis of a common language, territory, economic life and psychological make-up manifested in a common culture." Despite its brevity and crudity, this formulation incorporates a crucial cultural dimension overlooked by the other two Marxist accounts of racism. Furthermore, linking racist practices to struggles between dominating and dominated nations (or peoples) has been seen as relevant to the plight of Native Americans, Chicanos, and Puerto Ricans who were disinherited and decimated by white colonial settlers. Such models of "internal colonialism" have important implications for organizing strategies because they give particular attention to critical linguistic and cultural forms of oppression. They remind us that much of the American West consists of lands taken from Native Americans and from Mexico. Since the Garveyite movement of the 1920s, which was the first ma** movement among Afro-Americans, the black left has been forced to take seriously the cultural dimension of the black freedom struggle. Marcus Garvey's black nationalism rendered most black Marxists "proto-Gramscians" in at least the limited sense that they took cultural concerns more seriously than many other Marxists. But this concern with cultural life was limited by the Black Nation Thesis itself. Although the theory did inspire many impressive struggles against racism by the predominantly white left, particularly in the 1930s, its ahistorical racial definition of a nation, its purely statistical determination of national boundaries (the South was a black nation because of its then black majority population), and its illusory conception of a distinct black national economy ultimately rendered it an inadequate an*lysis. The fourth conception of racism in the Marxist tradition claims that racist practices result not only from general and specific working-cla** exploitation but also from xenophobic attitudes that are not strictly reducible to cla** exploitation. From this perspective, racist attitudes have a life and logic of their own, dependent upon psychological factors and cultural practices. This viewpoint was motivated primarily by opposition to the predominant role of the Black Nation Thesis on the American and Afro-American left. Its most prominent exponents were W. E. B. DuBois and Oliver Cox.
