What nonsense is this? If you want to create an ethnic divide in the Muslim world, then do not be surprised if other non-Arab Muslims also publish the truth about Arab 'kings, queens and princesses' to show how much they are in the foreground in spreading Islam or "subsiziding" Islam (whatever that may mean).
Trillion dollar investments by Saudi in kafir America while Palestine, Yemen, Iraq, Sudan, Somalia, etc Arab countries get a paltry few millions, not to mention the rest of the Muslim world. There is no need to remind the readers and members of the true nature and contributions of these 'kings' if they are familiar with it already.
Just keep the thread confined to 'investments' by your 'kings', no need to drag other groups into it, so there is no insult-fest later on.
