This situation is pretty bad. Even foreign born people of Pakistani descent should be careful. All the kidnappers know is that they'll get muchos rupees for handing over someone with a non-green passport, even if they're brown and have a 10 foot beard, over to the Taliban.
I believe the Shi'as of Kurram have copped it much worse than anyone currently, but alas, Pakistanis don't come out in droves to condemn them.
