The history of Blacks, Latinos, & Native Americans in the US has been systematically excluded from the curriculum & most American students get through advanced education without knowing a lick about that history. So much of Africa was Muslim, including during the Atlantic slave trade, so of course it makes sense that many of the slaves in the Americas were Muslims. But in my own studies I don’t recall ever reading reference to that important history.
