I am sorry your sensibilities get annoyed. I am not from other province I am from Peshawar. I am Qazalabash. I have personally seen racism by Pashtoons against non-Pashtoons. Anyone not a Pashton is called Punjabiyan and treated as a foreigner while we have been living here for much longer.
Punjab or Sindh is NOT an ethnic name. If Punjab was to be renamed ‘Alaqa-Jaat’ or ‘Rajputana’ because most landowners are Jats or Rajputs in Punjab the Arains,Gujjars,Syeds,Kashmiris, Awans and everyone would resist it.
Same as we would resist this being called Pakhtoonkhawa. A name like Abaseen or Khyber is fine. Both are not ethno-centric.
Balochistan name is also wrong. It shoudl be called Kalat as it was called before. If we change name of Frontier to Pakhtoonkhawa it will become another Balochistan very soon.
