Firstly the question is if this person who posted the original post is "targeted". By targeted I mean are people exclusively looking to kill him either because he has written something in the newspaper against the government or any religious or social group or any religious or political figure. If the answer to this is "yes" then he can have a case. If the answer to this is "no" then there are many Shias living in Karachi who are being persecuted because they are Shias, why not help them as well. What makes his case special? "What do you want Canada to do?". You want Canada to open their doors to all Shias who are being persecuted around the world? Why stop there, why not open the doors to other people being persecuted such as the following:
1. Burmese Muslims

2. Iraqis

3. 100 Million Christians

4. Syrian refugees

5. Ahmadi in Bangladesh

and the list goes on, my point is, is BaqarNaqvi a sought out figure in Pakistan? are officials after him? do they want him dead? By merely saying Shias are being persecuted does not help. This is a Pakistani problem and Pakistan has to take full responsibility of looking after its citizens, regardless of race, religion, creed, color, sex, disability etc. The report from press TV, the link that you provided on your post clearly says "families continue their sit-in for the second consecutive day in the city of Quetta demanding government protection" So lets get the facts straight and not get too excited about taking things out of context. You should question your government and your people first for your own safety instead of pointing fingers and blaming others in this forum for your misfortune.
