Sikhs are settled mostly in KP province and FATA. There has never been any issue with them. They are like us. no difference and they are also very well off. We love them and they love us.
In my hometown Mardan there are also some hindus and they are known for their honesty in business. They are also our brothers. and they are people of honor just like the Pathans.
But i fear if the current trend of radicalism continues esp from madrassas run by wahabi and deobandi sects, such a good environment of brotherly relations will suffer. not only sikhs, hindus and others will be targeted but they would target any ordinary muslim who does not believe or follow their faith.
we all are already witnessing that. I just hope GoP changes its policy on all the radical groups across the board.
