George Orwell, 1945 "Notes on Nationalism".
(i) Anglophobia. Within the intelligentsia, a derisive and mildly hostile attitude towards Britain is more or less compulsory, but it is an unfaked emotion in many cases. During the war it was manifested in the defeatism of the intelligentsia, which persisted long after it had become clear that the Axis powers could not win. Many people were undisguisedly pleased when Singapore fell ore when the British were driven out of Greece, and there was a remarkable unwillingness to believe in good news, e.g. el Alamein, or the number of German planes shot down in the Battle of Britain. English left-wing intellectuals did not, of course, actually want the Germans or Japanese to win the war, but many of them could not help getting a certain kick out of seeing their own country humiliated, and wanted to feel that the final victory would be due to Russia, or perhaps America, and not to Britain. In foreign politics many intellectuals follow the principle that any faction backed by Britain must be in the wrong. As a result, ‘enlightened’ opinion is quite largely a mirror-image of Conservative policy. Anglophobia is always liable to reversal, hence that fairly common spectacle, the pacifist of one war who is a bellicist in the next.
People have been like this for a long time and you're right, it's getting very, very old. I'll admit I like to paint 'leftists' or Guardian readers with a broad brush, on much the same lines Orwell did. I don't however try to claim moral superiority for it. How on earth you can claim to be culturally relativistic and hate poor white British culture while apologising for Islamic culture is beyond me. This is new to me, but there's a term for it: Particularism.
The odds have shifted to 2/5 for Conservatives to win the most seats, that's clear. The Sun have massively come forward for the Tories, it'll get more and more partisan as we get to the 7th of May. Who buys the Sun/Mail? Why, it's the white middle/lower classes. To believe that predictions of a Tory win are only possible because Sun readers are easily manipulated/idiots is stupid. To hold people to such a standard that they must agree with you on your every point of view is ridiculous lest they be ignorant or bigoted is ridiculous.
As follows: a non-rich white who votes Tory is an idiot who's been fooled by Murdoch propaganda and a non-white who votes UKIP is a self-hating uncle tom. How very fucking patronising by the same people who claim to champion the poor and the ethnic minorities.
