My understanding is that the breeding grounds for Black Muslim conversions in America is the prisons. It’s been a long time since I researched it so I don’t remember the details, but there’s quite a connection between Detroit and Chicago regarding Muslim “outreach” in prisons. The mentality of the criminal very closely matches the mentality of Islam, and Muslims are exploiting that by reaching out to a captive audience.
And the prisoners in our penal system know so little history that they don’t realize they are adopting the religion of their enslavers.
