This is a disappointment, it feels literally what he said so "I call it quits". I don't know who questioned his Pakistaniat, but to whoever I know he felt like a genuine patriot till he said that. I feel disappointed in him for throwing in the towel. What can be done? We aren't going to leave Pakistan with him, we know its quirks and faults, why tell us about his own failures to cope with them?
Oh well... Still many left to do the job. Khuda hi Hafiz.
A lot of 'extreme' liberals get their 'patriotism' questioned - Pakistan and Pakistanis are not unusual in that. Lets not forget the uproar in the US over the refusal of the French to support the Iraq war, and how many liberals who opposed war and the 'Patriot Act' were initially (and even now) labeled 'anti-American', 'unpatriotic' and 'communists', and were (and are) told to leave the US and go live somewhere else.
One doesn't see liberals leaving the US in droves despite that, so that part of his argument is a flawed one. Most American liberals chose to stay and fight (politically) and advocate for what they believed to be the right policies and laws.
George took positions on certain issues that rankled a lot of Pakistanis, and IIRC, his most controversial article did involve language that many interpreted as demeaning and derogatory towards Pakistan and Pakistanis, which, given his background, he should have been more sensitive to. It is no different in the US - there are certain things that Blacks or Jews can get away with, despite the language they might use, because they belong to that particular community, but the same argument by someone outside the community has to be phrased differently to avoid misinterpretation and insult.
We are not a color blind world/society, even in the US, no matter how much we may wish it, and to ignore that dynamic in public discourse is a mistake, which George made. Crying about it now and using the reaction to his mistake as yet another argument against Pakistan and Pakistanis is dishonest.
