It is a discourse that, drawing on a long discarded anthropology, essentialises such differences even as it claims to celebrate them. It is a discourse that was central to colonialism, slavery, segregation and apartheid. It is a discourse that perversely persists to the present, now manifesting in the way the media labels as "xenophobia" horrendously violent acts where some South Africans raise fists, swing axes and pangas, and use matches to light fires as means to attack their fellows who happen to speak different languages and allegedly look somewhat different from themselves.
 
We abhor the consequences of continuing and worsening poverty, unemployment, failed service delivery, and the global economy's effects and how they conspire to create extreme hardship for South Africa's vast majority, and to make attractive that essentialising discourse of difference. But we have to stress that never and nowhere can those conditions excuse violent unbridled attacks on fellow human beings.
 
We suggest that, contrary to the current South African and international political consensus, the presence of people who are deemed to be ethnically, racially or nationally different is not at the core of the problem; that the presence of so-called national, ethnic or racial minorities are no more the cause of uproar in Alexandra, Cleveland, or Hillbrow than they are of the ruthless hunting down in Naples, Italy, of people who call themselves Roma. The core of the problem lies, rather, in the fact of a system that breeds inequality, that marginalises people to an ever greater extent, and that then through supposedly "celebrating diversity", attributes their marginality to their alleged cultural, social and national characteristics. As Southern African anthropologists, we are convinced that closing borders and repatriating foreigners is not the solution. Rather the solution lies in a politics which explicitly fosters the non-racialism espoused by the South African Constitution, that rejects and resists the power of identity politics, and that strives for a cosmopolitanism that valorises the contributions of all who have ever settled in our part of the world whilst ensuring the freedom of association and of cultural and linguistic expression of all human beings.
