You know, it's kind of weird that you go on & on about this. You might feel some attachment to Lucknow but to think that your family & other muslims there support or must support Pakistan is beyond stupid. I'm inclined to think that your uncle felt sorry for you & your questions & he decided to humour you with what you might have liked to hear. Those muslims in Lucknow or anywhere else had their shot at going to Pakistan, your insistence that it is somehow okay for them to continue supporting Pakistan would be like pretty much asking them to die for this silly notion. That is pretty much what will happen if your family or any other made a comment like this in the open. To voluntarily want to be traitors, if indeed that is what they want, reflects poorly on your extended family. No one will have much sympathy for them & any fate that might befall them.
If you are unable to see that as being the result of what you seem to wish for them, then it does not reflect too well on your intellectual capability either.
