Are you deliberately trolling? Regions such as Southern Punjab are one of the main Islamist hotbeds of Pakistan.
Ever heard about groups such as Sipah-e-Sahaba Pakistan, ever heard of Zia-ul-Haq, some of our most retarded and prominent Mullah's being Punjabis etc.?
Here you have "neutral" sources (Western, who don't care about Sindhi, Pashtun, Punjabi whatever divisions in Pakistan)
There have been 1000's of terrorist attacks all over Punjab, are you seriously trying to tell me that all of them were the work of Pashtuns and Baloch? Sorry, but how naive are you exactly?
