Its unanimous in all records the greatest number of migrants settled in Punjab, while much less in Karachi. If what your claim of Pakistan aagey hai is true, then to filter ou urdu speaking from migrants and systematically displacing them towards kaarachi would require a huge, huge, huge machinery. Remember, the number of migrants was 5-7 million according to different estimates. No such machinery ever existed.
Correction, its not 'my' claim, its the claim of the people who were actually in the trains. There is a possibility that people who did 'Pakistan aagay hai' did it on few occasions (not 24x7) when they saw city getting too crowded by immigrants. Since there is no "video proof" on "Youtube" it is easy to discard anyway.
I find it quite amusing that a person like you can buy this crap,** its only possible if your judgement is clouded by bias**. I wonder how many people would it have taken for preventing your grandparents to settle anywhere from Lahore to karachi, with 3000 miles of journey.
Bias would come into play if I had any sympathies for the likes of MQM, I only paid attention to the surviving grand-parents. Neither I am in favor of ethnic discrimination nor provincialism etc. I only love Islam and Pakistan, thats my true identity.
