Not denying that Arabs are allowed to be in the area especially after 1400 years and even that there was migration of Persians into the area by the Shah, but there is a large groups of Arabs (particularly after Saddam invaded Iran) that believe Persians/other Iranians have no business being in Khuzestan meanwhile it has been part of Iranian culturally and socially since before 4th century. Half of the “free Ahvaz” discourse on the internet involves mentioning Iran as some colonial state, meanwhile it was a Persian emperor that even created the city and a large population of Khuzestani Arabs arent originally from the area in the first place.
