Good for the gentleman, he is good citizen of pakistan.
But I am not sure how the status sikhs in pakistan matches that in India. In India, they are not only normal citizens, they are leaders in many fields.
And taking into account partition, he should thank God that his elders COULD stay in pakistan.
If they had sided with muslims and became part of Islamic Repubic of Pakistan, they would have remained ordinary citizen only, technically having less rights than muslims. The fact that punjab would have been with pakistan would not help THEM in any way.
