Actually Sunni sects are a very real thing - but your being ignorant about it is not surprising, considering the state of the religion in Pakistan.
The very words you've written, are evidence of how far removed from normal Islam you nutcases are. Talk about, hateful, judgemental and extreme.
Call it wahabbism, salafism or whatever you want. It's a fact that certain movements have received a massive imbalance of funding in the past decades from ex pat's and middle Eastern countries. You probably think a lal masjid appeared organically in Islamabad.
You are foolish to think that you have somehow evolved in religion to your current beliefs - you are actually the victim of a sustained campaign and you don't even know it. People like you are the perfect patsies for enemies of Islam as you can be convinced to do anything to anyone with the right Islamic messaging.
