Former member of the NOI chiming in. As Salaam Alaikium.
Cosby indirectly defines success as strict anti-criminal personal behavior and safeguarding neghborhoods and communities. By that measure Black Muslims are decidedly more successful on average than most American communities. The closest equivalents I can think of are other groups with a strong ethnic ties and religious cores – like Orthodox Jews, Buddahists, Amish communities, Quakers, the B’nai B’rith, Latter Day Saints, etc.
Cosby’s holding up the NOI as an example to be emulated isn’t all that puzzling. For one, the Nation of Islam’s anti-white rhetoric has been toned down for decades now; simply because virulent racist actions against blacks aren’t as flagrant as they used to be. And despite their rhetoric, few members of the Nation of Islam have histories of violent, criminal and/or personally irresponsible behavior as long as they’re involved with the NOI. Although they have historically and continue to recruit members out of maximum security prisons, NOI members tend to reinforce behavioral standards between themselves, and self-destructive behavior (drinking, gambling, drug-use, whoring, pimping) is not permitted. The NOI’s success with reducing recidivism and ‘curing’ drug-addicts is well-documented. The tendency toward having lower divorce rates, illegitimate children and two-parent households is better than the national average. (Yes, I am aware of The Honorable Elijah Muhammad’s illegitimate children and Muhammad Ali’s many marriages. At least take a look at their personal conduct.)
In many respects the NOI is a law-abiding, conservative, disciplined, family-oriented organization that eschews criminal behavior even in former criminals it recruits – things that would appeal to Cosby. However a bigger issue with me with the NOI’s so-called anti-white attitudes is that it tends to be much more virulently homophobic than racist, insular, meritlessly patriarchial and gives lip service to members pursuing higher education and professional careers. (NOI is very blue collar.)
Despite public perception, the NOI as an organization does not preach virulent anti-white racism although Minister Louis Farrakhan clearly has issues with Jews and whites and says so openly when he’s assured reporters aren’t around and his audience agrees with him. But his bigotry does not necessarily filter down to the imams in individual masjids and mosques. And no, you’re not likely to see much in the way of interracial or interfaith marriage in a Black Muslim family, but that’s true of all the religious groups I mentioned.
Most people’s perception of the NOI is outdated, although I realize saying so is like assuring people, “No, no-- the Ku Klux Klan is different now!”
