Educated blacks are the real leaders of most African-Americans, and they are very traditional in their educational objectives. They are more likely to reject postmodernism in favor of the tried-and-true, and they recognize that social experiments that white pols have tried out have usually had poor African-Americans as "test patients" for whom the results are often catastrophic.
Add to this, older black people know what a disaster the drug scene is as white people don't. The current meth and opiate plagues are in places far from the urban ghettos as they could be. It is arguable that some of the people most hostile to drugs in America are elderly African-Americans who knew first-hand what drugs did to their peers.
