I have been to karachi for three months, they dont even have water for drinking or clean their pichwaras and wait for tankers with dirty water if that is development then we dont need that in punjab. Punjabis dont take trash examples to emulate , our dreams and objectives are more coherent with modern universal standards.
Actuall both have grown up in Lahore. But unlike kashmiris , the pashtuns living in punjab for centuries dont identify with punjabi ethnicity , that is also the reason why Nawaz sharif is regarded local man by punjabis despite his supposed kashmiri ancestary while imran khan is not regarded as local punjabi because pashtuns living in punjab live in this pseudo thinking that they are some kind of pashtuns despite having no clue of pashto language or pashtunwali culture of pashtuns.
In europe you are what your mother tongue is, so if your family speaks punjabi as their mother tongue then you are "punjabi" for a european. In europe it is quite simple Ethnicity = Mother language
