The true afghans are long gone - all is left is hybrid Nation of Arabs/Turks male ancestry and with the then Afghan women ancestry.
Afghanistan - 1000 years ago- was the learning centre of South Asia. After the muslim conquest - it became a hostile border region - all the learning centres were destroyed as where there true culture. Now - these people grow breards lives in caves - no difference to a cave man. Few month ago- there was an article - describing how oil painting was invented in what was ancient afghanistan (prior to the muslim destruction). If you read about ancient persia - you will also see how - Persia was a civilization that once rival Rome (Europe). But after the muslim destruction of persia- what is left is just sheep/cattle herdsmen with oil money - but no world class culture and civilization.
The truth is hard to swallow- Islam has destroyed what western and southern Asia - and has made Asia lag behind the European.
