:::::::::"Systematically killed" is POV. The armies in Tunisia and Egypt weren't attacked, yet they still shot protesters, Egypt shot more within the first month than were killed in Syria the first month, only after the opposition took up arms did the body count rise dramatically. Of course the clashes weren't sectarian in Libya, Tunisia and Egypt, since they're overwhelmingly Sunni. That didn't keep Christian Egyptians from being attacked by Salafists though. If the Shia of Bahrain took up arms as the Sunnis in Syria do, they'll be "massacred" too, no doubt about it. And the West wouldn't do a damn thing. Libya was more of a tribe-thing, though secularism versus Islamism also played a role. Secular Liberals in all countries were just the spice that ignited the unrest, they've had zero influence since, unlike what Western media tries to portray.
