In your question, You simply generalized all Pakistanis as hatred of USA. There are 175 million Pakistani living in Pakistan, do you think all of them are hatred?? If yes then I am sorry for your lack of knowledge and hurting all the Pakistani community specially on QL with your question.

For your information, those who hate US Government, they hate for reasons mainly due to it's foreign policies, I am sure they don't hate American People but their Government... and these negative feelings you will not only find in Pakistan, but in Europe, Asia, ME, Africa etc...

Also, before posting something do some research, Shareem Obaid Chiony is a Pakistani- Canadian not only Canadian.
She was born and raised in Karachi, Pakistan.
Do some Google and see what the world Media is calling her 'Pakistani' or 'Canadian'?
Hope you get the answer!!
