Re: ‘All Sindh residents should write Sindhi in language column of census form’
I dont think that is True or entire True. If some pathans and mohajirs who live in Punjab call them Punjbai thats on them, they are not forced to do so and it just means they assimilated for business, culture or whatever reason. However, you need to go in details to figure this out. My understanding is that Muhajirs that came from UP/Hyderabad or urdu speaking areas mostly were settled in Karachi/Hyderabad, where as the ones who came to Punjab were Punjabies from Indian side of Punjab. To this date, there is a sizeable Urdu speaking community in Lahore and Gujranwala and I actually know few of them. They may vote PMLN or PPP , may speak Punjabi but they are urdu speaking and more or less identify as such which is correct. For Pathans in Punjab, I will be very very surprised if they truly identify themselves as Punjabies. There is a pathan belt in Mianwali area who speak their language and identify as such, same goes for Baloch people around Dera Gazi Khan etc. They speak their language and identify as such (Siraiki, etc.)
In short, I dont think large majority of Pathan or Urdu speaking living in Punjab identify themselves as punjabi (rightfully so)
