All those things are in the book only. It is a fact that there is caste system in Islamic society also.Tthe "black" Omanis are not consiered as equals by the "white-skinned" Omanis. the equality you are talking about exists only at the time of Haj and prayer in the mosque. And of course The Quran says that "Khoresh" is the superior most tribe on planet earth.
I do not beleive in the dogmas of any religion nor in any god, but it is really irritating to see the muslims ridicule our native culture day in and day out as if there are no flaws in their religion. They should also understand that there are many people who are aware of their customs also.
I am quite sure from an unbiased reading of The Quran that it was the concoction of Muhammed to motivate his followers (with all those rewards in heaven or cruel punishments in hell, etc).
