Of course they are. If you actually read history the answer is obvious. Its actually far more entrenched than in white supremacist society.
I challenge any brothers living in the middle east to state differently.
What's weird is if you speak to men who live there or in Africa they know they are racist. They are still trafficking West Africans to their countries to use them as maids
today there are literally still young African kids from West Africa who are being trafficked right now (!). The way they treat Black Africans is barbaric. It is particularly shocking in countries where you've got the black ones and white ones. It is far, far, far more entrenched than white supremacy and I'm sorry to say but based on how stubborn and hard headed the black ones are they'll never be free because they've entrenched their hatred with racism so it means the black ones are still happy to serve and be enslaved under the rules of the religion.
These people need to do research. Rich people in UAE etc are legit still trafficking west Africans in today as domestic slaves (!) from Nigeria, Ghana, Congo etc. This is going on right now.
