There has always been racism from Arabs on (non-Arabs) blacks…as is shown elsewhere.
Sudan(black) has 20 times more people (50 million) starving and dying than Gaza (arab) (2 million) but all the ME headlines are only about Gaza.
Even blacks are racist to each other:
By their actions, South Africa and the African Union care a whole lot more for the Gazans(arabs) than they do for the Sudanese (black)
