Where are you getting these awesome statistics from? I would love to se the survey which says 50 % afghans are commiting crimes? As of december 2012 their 1.6 Millon afghans living in Pakistan. Are you seriosuly claiming that 800.000 People are involved in criminal activity and yet the goverment has done nothing about it? Yes, some of them are criminals but so are pakistanis.
Regarding them being Illegal? They were legal until December 2012 and then Pakistani Goverment refused to renew their visas. What are they suppoesed to do? Must of the Afghans living In pakistan have lived their for 30 years since the Soviet War and alot of them are bourn here. They dont have any place to go. Show some humanity. UNCHR is currently working on relocating them to Afghanistan and European countries. Between 2010-2012 over 200.000 returned to Afghanistan. They were victims of war, A war that they did not start. When they came to Pakistan they came under assylum.
Fix the problem. Dont throw it away like trash. For Instance alot of these Afghan Traders who were living in Peshawar were not paying Taxes earlier event though they were making millions? Now that is wrong. If you make money in a country, you pay tax in that country. Luckily Federal Board of Revenue was doing stuff around that.
They have taken thousands of low income jobs? Pakistanis have taken millions of low income jobs around the world ( I can not actually back this up but you get my point) so have the mexicans, polish, indians, Sri lankas,etc etc. Why should we be allowed to and not them?
Dont just state your feelings. I know its "Free Speach" and all. But Come on dude. They are probabaly some afghans here who can get hurt by reading your comments. Use Free Speach for good. Not to spred hate.
If you want me to back up my numbers with sources. Just state which and I wil be happy to except for that one I already told you about.
EDIT: You dont have to reply to this. You are entitled to your opinion. But Im not the kind of person who just stands by and watches. So I had to speak my opinion aswell. Hopefully you learned something useful by this and maybe your hate is reduced by 0.005 % then I know that tommorow this world is a tiny bit better because of me.
