Via Blithering Bunny - "Is the Guardian institutionally racist?" - the great Theodore Dalyrymple spells it out for the hard of thinking...
The people who run and write The Guardian have deep, suppressed and subliminal doubts about the equality of human races. To prove to themselves that they do not have such doubts, they overcompensate by publishing as many photographs of blacks as possible in their pages.
They don't have any such doubts with regard to the Indians and the Chinese. Moreover, these two groups have a horrible and fatal vice, as far as the mindset of The Guardian and its readers is concerned: grosso modo, these two groups can shift for themselves, and require no help from the coalition of intellectuals, moral entrepreneurs and bureaucrats in order to thrive. On the contrary, they are well on the way to outstripping the white population in achievement, thus demonstrating the redundancy of that coalition.
By contrast, blacks are regarded in the pages of The Guardian much as conservationists regard endangered species, in need of special protection. They therefore represent a goldmine for the coalition.
