Illegal immigrants, uneducated, mentally unsound.
I am not in favour of taking refugees, however I am against bad mouthing Afghans. Desperate poor and uneducated people do desperate kind of things, humans have innate desire to progress and wellbeing. But without education and training, that desire turns evil. UK, USA, Canada, Australia ask any country which has taken refugees, they usually exploit the heck out of the systems of that country. Its like a hungry person sees food and tries to eat it all at once. I sympathise with them for the bad time they have seen. But yes Pakistan can't afford to help right now.
