Both the rise of Islamophobia and the rise of Islamism have the same source: non-Muslims not knowing Arabic. If most non-Muslims would know Arabic, like most non-Muslims do know English, non-Muslims would be able to sort out the threatening Muslims(i.e. Islamists) from the non-threatening Muslims. Also, if most non-Muslims would have known Arabic, it would have been very hard for Islamists to take power. For obvious reasons, defeating or even exterminating ALL Muslims would make knowing Arabic even more necessary. So ALL people will have to learn Arabic anyway.
Note: Geert Wilders and Erdoğan agree that moderate Islam does not exist.
