Yes there is sizable support from the aam. The religious have braoinwashed the rest of Pakistan and it's getting increasingly radicalized.
You know this is something I do not agree with that the Mullahs are brainwashing. The issue of brainwashing has more to do with the people themselves and less the Mullah crowd. Just using the negative connoation of the word Mullah to refer to the so-called religious scholars is not a phenomenon unique to Pakistan, it is an epidemic that can be found in all countries. There are always religious fundos. In comparison people of other muslim countries do not have this issue as grave as it is in Pakistan though they also have similar Mullah crowd. The fault is in the people who listen to them and make them effective. The people in Pakistan do not have the enthusiasm to learn and properly follow the religion and consequently fall prey to such Mullahs. The root of evil is that people in Pakistan are full of rage and frustration and hopelessness. They fall pray to these Mullahs because they offer a way to release all that rage in the name of religion making it a justified cause. If the political and civil infrastructure in Pakistan had any transparency and accountability, such Mullahs would inherently get marginalized because people would not be as dejected as they are right now.
