One mistake that people living in other provinces of pakistan make about punjab is that they think that punjabis will tolerate instability in their provnice. They dont know that punjab is a society that believes in "Order" and "Stablitiy" at any cost and anything that will create "disorder" or "instability" is met with extreme hatred and disgust. Punjab is a society that has full capability to self-regulate itself to get rid of "disorder" creating scum which is not the case in other provinces, I will say interior sindhis are also similar to punjabis in this regard , you will also never hear any disorder in interior sindh. These are thousands of years old indus valley civilisations that cannot be fooled by rhetoric and emotionalism.
