They have never made it out of the tribal stage, that has to be pointed out. They might be on edge to turn into nationalism, but imho that is very far away. Even the current dealings show just how much tribal Afghanistan still is.
Naive to think of it as onesided. Especially with the last generation which grew up in the cities and could actually get some basic stuff, like education for everyone. Talibs are popular without a doubt. But they are also far from having an overwhelming support, otherwise you wouldn't see those masses of refugees going towards Kabul.
