I didn't see any "Afro-Iranians" in the original OP...All I saw was regular looking women...You wouldn't even know they were Iranian if the OP hadn't suggested it...
So, how exactly does being Iranian make those women more beautiful than any, if you can't even know they are Iranian?
A certain group of males just love them some light...Anything light gets and AUTOMATIC 6 on the dime scale...
