we cant really fault indians for having strong opinions about pakistan. pakistan did export terrorism to india. kashmir was perfectly peaceful 30 years ago but then pakistan started insurgency there. thats not the way to go about things even if pakistan claimed kashmir for itself.
So what did they do in East Pakistan? Anyway who cares what Indians think of Pakistanis, they are just damn ugly, smelly and ill mannered. BTW don't pretend that you are a Pakistani.
