The propaganda spread by Malcolm X and his ilk was that Christianity was the religion of the “plantation owners.” So any self respecting black had to reject Christianity and the West in favor of Islam.
What he failed to note, and unfortunately everyone else at the time failed to note loudly and clearly, was that the original slavers and slave traders were . . . Muslims.
It was Muslims who took those blacks and sold them in the first place. As they had been enslaving people for a thousand years previously, including white Americans and Europeans. American slave owners were relatively late to the game, and it was Christians, basically, who ended the slave trade and freed the slaves.
Things you won’t hear from the MSM or the academic historians. Nor will you hear that it was the Democrats who enslaved and Jim Crowed the blacks, and Christian Republicans who freed them.
Christians certainly were guilty, for a time, in the enslavement of blacks. But it was not Christianity who taught them to do it. In contrast, Islam DOES teach that it is good and virtuous to enslave your enemies, as Mohammed did.
