Yes, it's a fact that Arbis fund terror in Pakistan, but it's also a fact that Pakistani society accepts the Islamism that has been imposed on it - nobody has forced Pakistan or Pakistanis to be victims of daily bombings and killings, in the name of confession, sect and "Islam in danger" --- fact of the matter is that most Pakistanis cannot tell the difference between Islam and Islam-ism, in fact if they had a choice, they would choose the most brutal and backward among the two -- let Pakistanis learn in their own time and in their own way, they will either learn or go the way of the dodo.
In the meantime there is little we can do but to raise awareness. If Islamism unites Pakistan, and if these are examples of that unity - well, then, it's doing a "bang" up job.
