I think you make an too easy argument: Compared to e.g. Christian places in Europe where people still the same tongue like before the Christianisation (roughly speaking), Aramic, Demotic or Berbic languages, once majority languages are now minority languages in Arabic enviroments. Ironically Aramic and Demotic are spoken mostly by Christian minorities.

Also I see the Islamic movement in recent years pushing for Islamic homogeneous countries and driving ethnic, religious, language and sexual minorities out of their homelands (mainly into Europe).

Compare to today (often secular) European counterparts Arabic nations are homogenous and root cause was Anti enlightenment ideologies.
