I also remember a discussion online (I think it was Guardian CiF) in which a Muslim was talking about how at his local mosque, Somali, Bosnian and Nigerian and Pakistani and Bangladeshis prayed side by side, and this proved the universality of Islam over all other faiths, because they represented so many different ethnicities - to which someone replied - you don't even consider 50 % of humanity to be worthy of entrance into your place of worship, so shut your mouth. To which he spluttered something or another, but it had left him for dead.
They might pray side by side with Somali & Nigerian Muslims, but Indian & Bangladeshi Muslims can be extremely racist towards Black people,whatever their ethnicity.
In fairness to them,
most Indians, whatever their religion, also very often show the exact same prejudices towards black people.Also, they can suck up to Whites big time.
My father had friends from various African Embassies in Bangladesh, who often spoke about how they encountered racist attitudes pretty frequently. My Bohra Muslim grandaunt, whose daughter has gone to study in USA, told us the other day that she'd be fine with a prospective White son in law,
as long as he convertd to Islam, but can't even contemplate a Black son in law & has warned her daughter against dating blacks!
Although the Quran isn't racist, there are some racist statements in both Ibn Ishaq's Sira, & of course in Tabari-claiming black people look like the Devil or are destined for slavery. Islamic history too has often been extremely racist towards black people, the Islamic slave trade in Africa continued for a far longer time than the Western slave trade in Africa, & it included abhorrent practices like castration & mass abduction of small children, which meant millions of black people captured by Muslims could never reproduce & increase their population in whichever Islamic lands they were carried off to, unlike black people taken to America, where the black populqation rose rapidly & which has millions of black people in extremely prominent positions today.
One of the biggest myths Islam managed to successfully perpetuate, imo, is the myth that it has no "racist past," although Muslims are responsible for a far bigger Black Holocaust than Whites, through many more centuries of slave trade, child slave trade & especially castration.
