if you're serious about decolonization as a concept, rather than a buzzword, you should fully comprehend that dearabization and deislamicization need to be placed at the conceptual core of decolonization, and the means everywhere where arabs and islam acted as a colonizing force; it means in both north and subsaharan africa, in the middle east, in eastern europe, in india, in iran, in central asia and in south-east asia. arabs are only indigenous to the south of the arabian peninsula, the area near yemen, and islam is only an indigenous religion in the deserts of arabia. it is a colonizing, imperializing force everywhere else in the world. 

if you don't include dearabization and deislamicization in your concept of decolonization, you are not serious about decolonization, you are just using the language to enforce and implement some other ideology, like arab supremacism, like anti-semitism or like islam itself.

in israel, what decolonization means in an actually coherent sense is dearabizing the genetically hebrew indigenous population, as it is arabs that colonized the region in the name of islam and that is what needs to be undone to decolonize it. palestinians are jews that were colonized by arabs and converted to islam, and they know it. that is what the truth actually is.

further, if you are a jew, you should realize you will attract more flies with honey than with vinegar, even if that looks difficult now. your grandchildren will thank you for making the effort.
