Dr. Atif told a very logical thing on this matter in another thread (like this)- Pakistanis think Afghan Taliban are real Mujahideen because they are on the other side of Pakistan's border. But they don't accept TTP completely because they are inside of Pakistan. I've seen among many Pakistanis that they appreciate the present system of the country. They don't expect complete Shariah implementation.
But could I ask what exactly these experiences have led the people you mention to think that TTP are not 100% and so forth?
