africa/global: The global hierarchy of race

Racism everywhere remains largely invisible and hugely under-estimated, the issue that barely speaks its name. How can the Economist produce a 15,000-word survey on migration, as it did last year, and hardly mention the word racism?

Why are the deeply racist western attitudes towards Arabs barely mentioned in the context of the occupation of Iraq, carefully hidden behind talk of religion and civilisational values?
