Are black muslims aware of the role of Islam in the slave trade?

The African slave trade (triangle - tobacco, rum, slaves) was a bit more sophisticated than that but yes, Africans, Arabs and Muslims (of both groups) were part of it. Obviously the slaves in these scenarios were already slaves of the Arabs/Africans (to do with as they saw fit). Of course, no one from America (or some European nations) would make the journey to the West African coast and return cargo-less so the traditional concept of catching/enslaving free Africans would also be deployed when needed.

Human slavery has existed for at least 4,000 years (and I am being very conservative in my estimate) and apparently on every habitable continent. Spartacus tried to end it in Rome 2,000 years ago. Ultimately, these Caste Systems do irreparable damage to both servant and master alike. A system/civilization built upon it will either crumble or reform (painfully). America's bloodiest war was fought over it.

And if they really want reparations, their first stop should be their own people in Africa, then the likes of Saudi Arabia and Iran, and last whitey back home.

Because even a simple google search will turn up vast documentation on 2 inconvenient facts:
1.- African blacks were mostly captured by their own people (rival tribes) whom realized it was way more profitable to sell rather than imprison/kill their rivals/criminals/prisoners/whomever.
2.- Arab Muslims commanded and manned the slave trade routes, thus effectively becoming whitey's slave provider (and of their own societies whom some STILL TODAY practice slavery).

So if blacks think that Christianity is the main force that enslaved them and Islam is the main force that can liberate them, they've been bamboozled, to borrow one of Malcolm's zingers.

And if they really want reparations, their first stop should be their own people in Africa, then the likes of Saudi Arabia and Iran, and last whitey back home.

Just stop with the fake sanitized history just stop it. Accept your races role in the bondage of an entire people and pay your dues.

They are almost certain not to know that the prophet owned black slaves that he referred to as 'raisin heads'. If blacks really knew the history of Islam none would be a Muslim.

Probably because slavery isn’t encouraged by the Quran. So it doesn’t really have anything to do with Islam.

You missed "The Rules" meeting.

Let me sum up:

White man bad. Mmkay.

Black man sold black man. = OK

White man sold black man. = EVIL

Jewish man sold black man. = OK All is forgiven.

Nope. Most don't know anything about Islam beyond the tripe the media tells them, like saying it's the religion of peace, and showing off the artwork and sanitized crap in documentaries/history books. They also have never been taught anything outside the twisted narrative that only white people in America kept black slaves, and that's that. They think that's all they need to know about the history of their ancestors being enslaved.
