Their grievances are genuine. Punjabi(including some Potohari) politicians have long exploited their resources. To win votes, peindu uneducated MNAs brought gas connection to even the most unproductive shitholes of Punjab like Sargodha(of all the places). Their gas field in sui was virtually dried out by us. I'm also a big critic of the passive aggression and imperialistic attitude of the Punjabi(central Punjab) elite.
With that said, I highly disagree with things like killing random labourers and poor people in general. It's good that they(Baloch insurgents) have abandoned their leaders, who became naive pawns to the unfriendly intelligence agencies. With that being said, central Punjabis should think about what their leaders are doing, and try and stop them. Unfortunately, I've met some really ignorant and imperialistic minded Punjabis in Pakistan.
With that said, I've got nothing against the average Punjabi(central). It's just their corrupt elite, which puts self-interest above that of the federation. This imperialistic attitude is found in other influential regional communities of Pakistan as well, for example ANP etc.
