The heavily religious communities in the early US didn't display any of the tribal behaviour commonly seen amongst the Taliban (which are the cause of most of the governance issues in Afghanistan), just the extremely strict adherence to religion which is in some ways a superficial similarity as the average person in those times was as fanatically religious as only the most hardcore Christian today.
For instance Cousin marriage wasn't a thing at all (which is one of the main ways of maintaining tribal cohesion) while it is still extremely common in Afghanistan and the Middle East today.
