racists attempting to excuse their racism and privilege

I think Arab Supremacy is not talked about enough and it is something I feel strongly about. Racism in Arab countries against South Asians and East Asians, as well as black people is seen as common and expected. It is normal for staff to treat customers who aren’t white or Arab themselves poorly, and not to mention the horrific treatment of the domestic workers and construction workers, who are completely ignored and basically have very little rights once they start working for Arab families. Racism in Arab countries is swept under the rug and tolerated. Arabs adopt a mentality similar to white people and develop superiority complexes, this has a lot to do with their skin colour, as anti blackness is rampant in Arab culture as well. It is so common to see blatant racism from Arabs openly on twitter and there seems to be little to no backlash. Why are they excused from their racist views?  
There are documentaries made about racism in Arab countries, Lebanon being infamous for it’s racism as well as the Khaleeji states (U.A.E, Qatar, Bahrain) whose ugly truths are hidden behind their attempts to constantly show off their country as luxurious resorts. White people visiting these countries (especially Dubai) will LOVE the way they are treated, because they come only second to Arabs and retain their white privilege. However, people with more melanin (especially Asians) will find their situations are not the same.
