Wait what? How many African Americans have you actually met, or even know personally? I know quite a few and being religious or being Christian is not a strong point of theirs anymore. It was, but most are impartial to faith. So your whole point makes no sense.
You literally just side stepped my point about their disconnect from their land of origin, which played a huge role in the faith they were forced to adopt (Christianity) in the US. The same cannot be seen in other black populations living in western countries which are black and Muslim e.g. the UK, France etc.
They came from the same land you did. What are you suggesting, he hops off to Arabia because of his faith?
