I'm disturbed that you're considering rejecting something just because it was written by a Social Democrat, and at the same time talking about politics being the mindkiller.
The charitable interpretation is that Orwell is known first and foremost as a political thinker, and there's evidence that his 'nationalist' biases were present on the things he cared about.
