The term in my experience has been applied to Black men and particular two types of Black Men. It s easy to see why Gangsta types would be considered a nightmare. With generally anti-social behavior they are a threat to America and the Black community in particular. America has developed a response to gangstas with tougher law enforcement measures. Men with brains are supposedly a real threat to America.
Success is always the best revenge.
These so-called educated brothers are not a real threat because many times these brothers buy into the system with homes in the burbs and married to white or bourgeois women. They are not the American Nightmare. They are the American Dream. There is another group of brothas in American society. Their numbers are small but growing slowly.
