MQM and violence is a very new phenomena, one that was pushed by the jihadis, ISI, and Taliban godfather Nusrallah Babar. From the Pashtun tribes, their history of death and violence spans hundreds of years.
The difference between your tribes and parties like the MQM is that we (most of us anyway) learn from our mistakes and try to better ourselves, while you lot continue with your ancient battles over fictional “honour”. Better to be a Shudra than to be one from the beheader caste.
Pashtuns are not half as honourable as the myths about them try to portray. Fact is that like most people, they are fallible.
