Well to be rude to someone, means you are considering yourself to be better than this person ! i.e. arabs think they are better than others? well first we need to define arabs !
by arabs you mean the people of the gulf ! lebanese, palestinian, syrian, tunisian .... are all considered arabs but they defer to the gulf people in every way !

the misconception of having alot of money and thus making you better than others is very common in the region, unfortunatly for them, the level of which a society is measured is not by how much money each induvidual has ! but by the education and contribution to this world!
so if arabs are rude, then let them be in their own dreamland ! thinking they are better ! but a great philosopher once cais:" what goes around, comes around"

i rest my case !
