Failing to learn the lessons of the "Auden generation"?

Nick Cohen recounts his excommunication from "the left" and decries some of the failings of the contemporary progressive movement:

Auden noticed a retreat from universal principles in the 1930s - communism was fine in 'semi-barbaric' Russia but would have been a screaming outrage in a civilised country. He should have been alive today. With no socialism to provide international solidarity, good motives of tolerance and respect for other cultures have had the unintended consequence of leading a large part of post-modern liberal opinion into the position of 19th-century imperialists. It is presumptuous and oppressive to suggest that other cultures want the liberties we take for granted, their argument runs. So it may be, but believe that and the upshot is that democracy, feminism and human rights become good for whites but not for browns and brown-skinned people who contradict you are the tools of the neo-conservatives.

On the other hand when confronted with a movement of contemporary imperialism - Islamism wants an empire from the Philippines to Gibraltar - and which is tyrannical, homophobic, misogynist, racist and homicidal to boot, they feel it is valid because it is against Western culture. It expresses its feelings in a regrettably brutal manner perhaps, but that can't hide its authenticity.

The result of this inversion of principles has been that liberals can't form alliances with the victims of al-Qaeda in Afghanistan or Iraq any more than the Auden generation could form alliances with the victims of Stalinism.
