May be not all but....
They are fanatics, organized, armed and trained by IRGC.
They run hate classes and hate parades in Pakistan openly.
They flag their houses, cars and wear attire which is all sectarian.
Credit to Zardari.... when on govt. or private job, there mission is to fill that company /dpt. with people loyal to Iran and eventual take over.
In general elections, they vote ONLY PPP, which is busy taking revenge of false history from Sindh, Pakistan... as we speak.
The moment they are out of the Pakistani boundaries, their best friends are Indians and their worst enemies are Pakistanis.
While in Pakistan they try all in their means to dictate Pakistan and Pakistanis. They gang up when ever Iran order them, their mission is to weaken, malign and hurt Pakistan. They harass common Pakistani, accuse him, abuse him, and no one would come to help. When in street, they can kill any one openly, and would even record that killing for their own masters. Pakistan police stay away or some times provide security cordon, while they are busy in vandalizing, killing, burning, destruction.
They have ZERO tolerance for sect. less Muslims.
You might have seen their brutally, when they were killing children of Rawalpindi Mosque.
They can destroy public property, block roads, carry sectarian banners, pagan rituals in front of your children and may even term it Islam /revolution /nia Pakistan... but you can't do diddly.
They have
reduced Pakistan to a satellite state of Iran, where every person term Pakistan as an enemy state.
ALL of them go to Iran and Iraq for militancy training, over and over again, yet no security agency dare to ask a single question, when they cross border. One must wonder... why than immigration ask questions to rest of us!
In Pakistan some invisible foreign power is arming them, which they hide under ground for the forthcoming revolution which they are cooking.
