Why this victim mentality? So doors are shut only on Pakistani immigrants, not others?... I have worked in many western countries besides being born in NZ and now living in Oz....one common factor among immigrants from the subcontinent, is lack of willingness to involve and integrate with the local culture and society...even though they are born in that country, the family/social mindset do not allow them to mix and adopt local cultural aspects and thus they remain alien ... same mindset leads to different behaviour of these kids and is one of the reason of being discriminated by the larger society.
In general, we should stop thinking, viewing, behaving with others by keeping religion at forefront....sooner we do it, better accepted we will be in other's society...and if we can't do that, it's better to stay where they are rather than migrating there.
