Pakistan did accept all the refugees which were allowed to travel to Pakistan in 1947.Most of them who were totally defenseless,hungry, poor,walking on foot;on backs of donkeys,overloaded trucks and trains were brutally massacred by the brave Indians.
Nobody asked Hindus,Sikhs to leave Pakistanin 1947.Those who stayed in Pakistan are just as valued citizens like the rest of them.
Then India created Kashmir problem,agreed to plebiscite and reneged,massacred another 80.000 innocent Kashmiris in fake police -military encounters,kidnappings,extra judicial killings no diferent than killing about 100,000 Sikh youngsters during days of Khalystan movement and organized discrimination of Sikhs ever since; posting 500,000 military troopers in Kashmir to suppress the political voice and conscious of the Kashmiris.
USA can attack sovereign countries like Iraq and Afghanistan,kill one million Muslims since 1990 and it is not terrorism.
The only means Muslims have to fight back the war thrust upon them is through suicide bombings.When Muslims fight back with the only means they have,they are labelled as terrorists.
If self defense or defense of your country is terrorism,then so be it.
