There's every reason to bring race (and sex) into it, because white males have held the Faith in a stranglehold of privilege and power for so long. The OP's poor mother has been browbeat by the system into believing that the resulting twisting of the Faith is "the Way It Is." The message need to be put out there that Xy does, indeed, belong to the black woman.
Personally I prefer skin color blindness. I'd think the message should be that Christianity is available to and belongs to everyone.
If we continue to promote differentiation because of skin color, everyone else will as well.
