So-called Black Muslims labeled themselves. The movement began in this country in the '60s.

Yes. And, more likely than not, they were motivated by leftist anti-capitalist ideology more than religious faith. More of Lenin's malcontent "useful idiots". That's all.

Here, here. I've suspected for some time that the Muslim aspect was merely being used as a shield to protect their anti-American, Marxist views. Freedom of religion is indeed a many-edged sword: you can hijack a religion, twist it, and use it to push agendas that not only conflict with it, but in reality have nothing to do with it.
