Every person migrates to some place at some point of time. Sindhi & Kutch are different languages just like Punjabi & Sindhi,Kutch had a majority Hindu Population just like Junagadh & Hyderabad(Deccan).
What about the Muslims bought by Afghan invaders,turkish,Iranian,Central Asia.Why r u silent on that.
Amarkot had a 80% hindu population during Partition,today it is less then 30%. Where did the vast majority of Hindus go,did it disappear.On the other hand the Muslim population is increasing in India year by year.
So I still feel atleast 50% of Karachi should have gone to India.
