I see two issues here. The first is, "Who is a good Pakistani citizen?" and the second, "How does one judge who is a Muslim?"
Whether or not the Ahmadis are considered Muslims I see no basis to pronounce that they are, collectively, bad Pakistani citizens who must therefore be deprived of their civil rights - and we're not just talking about felons deprived of the vote (as in the U.S.) but of people deprived of property, art, state protection, and due process of law.
This is the route both Nazi Germany and the antebellum American South took to oblivion; once political or religious opponents were proscribed, terror and bigotry seized the citizenry as they realized anybody could be labelled as such, merely on a whim. The power inherent in that sent thrills of terror or power through individuals and created the atmosphere for civil and external war.
My question for Pakistanis here is: how can you justify your personal inaction here? Why are you doing nothing but sit on your ***** rather than demonstrate in the streets of Indianapolis or Islamabad to oppose this?
