Hmm wang man its not that i am disagreeing with the motive of your post,but the mere fact that you used Afghanistan as a example is actually quite wrong.I have been involved with Afghani people in the past,and they are one of the most strong willed people you'll find in the world,and one of the most physically skilled ones.And they wont treat a person who has hair like the OP the way which you have suggested,since you would find even Afghani people with weird hairstyles.
Anyway if the OP is okay living with his hairstyles then it shouldn't concern anyone,since it is his life,and his decisions.But from my personal view,it should be a little trimmed otherwise it has kinda little freakish effect on me,like he is on some kind of medication or something.
P.S i also find human autonomy interesting
