Sikhs are recent arrival. Pashtuns were here long before them. The name Hazara we use in everyday conversation. We refer to people who are mixed and do not belong to a specific tribes. We say in Pashto “Da Hazara dee” meaning that these people are hazara we don’t know their ethnicity. The same apply to some people in Afghanistan. Those people are actually mongolian but they are ashamed of that and that’s why the pashtun in Afghanistan named them Hazara. I still think Hazara is very insulting we should change the name to Kohistan or Abaseen. We don’t need to make in ammendment to the constitution, a simple majority in Pakhtunkhwa assembly is all that we need to change the name.
