Translation: 

steve_d1 has no argument that the court decisions dealing with how Khadr was treated are wrong, or that the recent negotiated settlement isn't legally advisable.  

Instead of sticking up for the decisions and the courts that made them, or  the settlement, he's going to try to justify inflamed public opinion by making fun of the "cloistered variety that seemingly lives exclusively within the interpretations of the Charter."  And by pointing to "the Khadr family members."

It's a deeply cynical approach.
