And who gave you the right to interpret Islam the way you are? Political unification is not the purpose of Islam neither that is possible as evidenced by the political history of Muslims who never were united except for the first 40 years of Islamic rule when the Ummah had not yet expanded. Today there are 55 Muslim countries because different people want to live according to their traditions and culture…
Moreover, have you met every single Pashtun to make that ridiculous claim?
In fact, those that suffer from identity crisis shout Islam, I agree with Marwati.
