In many European countries it is reported that half of the rapes are committed by Afghanis. Other muslim immigrants are on the list too, but not as prevalent.
Afghans general population is illiterate therefore they function mostly by feelings/emotions which are highly distorted for the Islamic teachings they’re programmed to from childhood to adults. Their natural God given personalities have been snuffed out by Islam.
Sooo.... placing them into Western cultures the cultural shock will be off the scale. And they certainly will not adjust well.
Remembering the Radio station where a highly functional Afghan beheaded his wife for wanting a divorce and others like this evidences that Islam remains a death cult wherever they are.
