Sorry, what I meant was indo-iranian group or iranic people. They are indo-european but not Indo-iranian.
Right. Like I said before they are still close to Pakhtuns due to regional similarities. It's a similar situation to Nuristan in Afghanistan, where Nuristanis might not be Pakhtun, but they are still integrated into the local region.
I don't think we need to use Karachi as an example because many people there think that every Khan is Pakhtun and can't tell the difference between a Gilgiti and a Pakhtun.
