Ethnopluralist

Ethnopluralism or ethno-pluralism is the acknowledgment of the diversity of different ethnic groups. Ethnopluralism brings together the philosophical doctrine of pluralism (often referred to as the doctrine of multiplicity) and applies the concept to ethnicity. 

"Cultural differentialism" is the view that cultures are clearly bound entities with a specific geographical location. From this perspective, global cultural diversity takes the form of a cultural mosaic, with a multiplicity of diverse cultures clearly delimited and with strict boundaries between them.

Ethnopluralism goes against liberal multiculturalism and emphasizes the separation of varying ethnic and cultural groups, in contrast to cultural integration and intra-cultural diversity. According to ethnomusicologist Benjamin R. Teitelbaum, the term "ethnopluralism" was first coined by German sociologist Henning Eichberg in an essay that was written in opposition to both Western and European eurocentrism. It has been part of the ideological foundation of the European New Right, which has used ethnopluralism to express its favoritism towards the cultural identity of individual groups, thus expressing its opposition to heterogeneity within cultures. As argued by many supporters of pluralism (which denotes a diversity of standpoints and systems rather than a single one), this sort of integration and diversification is likely to be a problem for societies of multiple ethnocultural groups that are oriented around the idea of separation as a means of a more cooperative integration.

Ethnopluralists use the concept of cultural differentialism to assert a "right to difference" and argue for regional policies of ethnic separatism and racial separatism, but stress that each ethnic group and racial group should be considered equal on its own merit. This right-wing view of culture, ethnicity and race has become increasingly popular in the ideological discourse of several right-wing and far-right groups in Europe since the 1970s, and has penetrated the discourse of a postmodern Left (i.e. Telos).
