Of particular note is John Gledhill's - "Beyond Speaking Truth to Power: Anthropological entanglements with multicultural and indigenous politics" (pdf) which looks at the problematic role of anthropologists in representing the claims of indigenous movements.
[T]hese problems have been exacerbated by the fact that specific types of “pluralism” have now become integral to the redefined state projects of the neo-liberal era, and are, in a closely integrated way, also frequently integral to the strategies of political and economic forces that have far from “progressive” social agendas. We need to ask how far greater “pluralism" relates to both conscious tactics of “fragmentation” of popular movements and how far “fragmentation” is a bottom up response to changing socio-economic conditions that need to remain at the centre of our analyses.The paper is part of an ongoing discussion on minority rights and the use of the term "indigenous", and includes a brief summary of Adam Kuper's critique of the indigenous rights movement.
