To be fair, pre-Islamic archaeology in Saudi Arabia is maing great strides in recent years. Though of course this does not apply to Mecca and Medina. The Saudi government does not seem to be using that for legitimacy, and I would be somewhat surprised if they did, but it's not like they are deliberately destroying traces of their past (they do when there's money to be made out of that, however, that mainly concerns Islamic sites).Sure, you can separate it. Just as likely you keep them together though. Mainly you say that you are the center of the Arab world or the best for running stuff. Plenty of Islamic states (I know they aren't all Arab) use propaganda that stretch back to pre-Islamic and pre-Arab histories. Saudi Arabia being one exception, as they demolished everything the rulers and their supporters thought connected too far into the past, plus a great deal of Islamic sites.
Relatively limited. Some hundred loanwords, some influence on syntax, not much else AFAIK.How much Coptic influence is there in Egyptian Arabic nowadays?
Very difficult after about 1000, AD as the majority of the population would be both Muslim and (vernacular) Arabic speaking, and most Christians (and basically all Jews) would be speaking some sort of vernacular Arabic as well, and largely using a form of Arabic (at some times, Jews would be using it in Hebrew script; Christian Arabic also had less Classical features) in writing too.Could rule by an Islamist Arab conqueror discredit Arab-Islam?
I think a successful Egyptian state under Muhammad Ali Pasha and his descendant can be a possibility, for example no Abbas Helmi I and in his place a more reform minded Khedive.
Although one could argue that the marginalization of Copts during the last millennia didn't help in preserving much of the substratum, especially in the Delta.Relatively limited. Some hundred loanwords, some influence on syntax, not much else AFAIK.
