In response to the same Guardian article as previous post.
We need to recognize and develop an understanding of the POWER politics of mass immigration and multiethnic society, which isn't just about the provision of cheap foreign labour for state and capital, but also about the imposition of a racial IDEOLOGY (the exact, but equally extreme, opposite of Nazi racial ideology) which the STATE uses to claim a spurious "moral high ground" for itself, in order to facilitate its control of society, just as Christian ideology (theology) once was, and as Islamic ideology (theology) still is in most Muslim countries.
It is the ideology of "one-human-race-ism", of "colourblindness", of "indifference to ethnic difference", of "race doesn't matter", i.e. is of no social or political significance except to evil "racists".
But far from being of no social or political significance, race and ethnicity have always been, and still are, of central importance to any deep and meaningful sense of personal and group identity (because we evolved as TRIBAL animals), vital to a genuine sense of nationhood (as opposed to statehood), the natural extension of our original TRIBE, and social solidarity, which cannot possibly arise spontaneously (except towards individuals) in a multi-ethnic society, but has to be imposed by moral imperatives from above, which the state then uses - is using, massively! - to control society for its own ends.
The problem is that so many people (currently, the vast majority) identify with the STATE, and are rewarded for doing so.
