This is a response to my bit about Anatolia and Greece not using Arabic right?
Well, those churches managed to maintain their languages and scripts even if just as lithurgical and household language and in the South Caucasus were Arabization was limited to like cities, those languages and scripts remained dominant.
I don't see Arab migration into the Anatolian or European country side, so that means Anatolia and Greece would more resemble the South Caucasus than Mesopotamia in language. At least, up to 1000 AD if the conquest happens in the 600s.
I intended to address your rebuttal of the notion that convert communities maintained their ethno-identity, in which you cited examples of Christian denominations in the Middle East.
One must consider, for example, that the compromise of identity that Aramaic-speaking converts experienced can be attributed to a myriad of factors, including lack of economic self-sufficiency, absence of tradition of statehood, lack of a defined area of habitation etc. Rather then the existence of a consolidated Church structure, it was these factors that effectively inhibited the emergence of a Syriac Muslim community. The Arabization of converts in Syria was also facilitated by a historical and long-standing presence of Arabs in the Eastern Mediterranean, even prior to the advent of Islam. The Greek community, akin to the Persians, have historically maintained economic self-sufficiency, as well as a tradition of statehood through the ERE. Therefore, it is flawed to state the lack of a Aramaic/Syriac Muslim community is indicative that Anatolian converts will abandon a Hellenic identity as the circumstances are quite differential and can not be reconciled by referring to a consolidated Church community.
That does not necessarily mean Arabization will not occur, more so that is likely to be a more gradual process. The conquest of the region will mean that Arab garrison towns will be founded, particularly in the face of Christian or Kharijite/Shi'i agitation.
I think the chances of with more Berber recruitment needed, the racism against Berbers specifically would drop.
Berber recruitment increased significantly towards the dissolution of the Caliphate of Quruba, little indication exists that this mitigated the ethnic hierarchy of Al-Andalus.
