I think most Pakistanis like myself have absolutely no problem with Bangladeshi people. However its a different issue as far as your government championed by Hasina is concerned (who sees ISI and Pakistans hand in apparently anything negative that happens to her, didnt she blame Bangladeshs cricket defeat to Pakistan in the Asia Cup on ISI?). Thats where most animosity of Pakistanis towards Bangladesh is emerging from. Take her out of the equation and you will see Bangladesh-Pakistan ties improve immediately.
Actually, Pakistanis need to think beyond the political issues because what the politicians say is not always what the public thinks.
