Re: Taliban are Kharijites?
Hard to compare the Taliban V the kharijis. One similarity could be their anti-authority stance. Their story is a long story of of drug money, international jihad and a long afghan war, foreign funding and meddling in Afghanistan. The book "Taliban by Ahmed Rashid" gives quite an insight into both the Taliban and Alqaeda. Highly recommended.
View that the Taliban are on some sort of divine mission is hopeless.
