I wonder what the Islamic jurispudence behind this is given that enslaving other Muslims is pretty explicit haram afaik, but then again Afghan Islam is like Chechen Islam in that it is built on top of the original moral systems (Pashtunwali/Vaynakh)

For Americans, the point of this is not even that this is what "conservatives" want; it is that, to the peasant mindset, this is the only way a society can be run or ever has been run, and the Afghanis are just being honest about it.
