You should also ask from Karachite that why they always been voting for MQM?
I am Photohari but How Punjabi automatically become nationalist if they choose to vote for PPP or PML(N) ? How?
PPP have been popular in Punjab in the past and they were Sindhi
voting certain party is the only criteria to prove that whether you are Punjabi nationalist or not..How voting PTI will be any different when same left overs of PML(N) and PPP joining PTI in Punjab i.e Firdous ashiq awan, mahmood qureshi, jhagir tareen, haleem kham, Nazar ghondal, Noor alam, Liaquat Jatoi, Mustaf khar etc
Punjab have accommodated different ethnic groups from all provinces with open arms and we cannot say same for rest of provinces where Punjabi population have not got opportunity to settled in there along with Pashtuns, sindhi or Blaoch who prefer their own community and avoid mingling with others ethnic groups
I also dont see any political party in Punjab who advocate Punjabi nationalism or separate Pujabistan unlike some in others provinces who prefer this idea Pashtunistan or free Balcohistan
