I've searched and found this article:
"According to UCLA Hospital psychiatrist Dr. Ernest Bloch, the distorted sense of reality exhibited by many rappers may indicate a predisposition toward a wide range of serious mental disorders, including schizophrenia." (emphasis mine)I consider it disrespectful. Perhaps their aim is not humor. I'll have to check it but what if I find out that some of their editors are psychopaths?
"Many of these rappers create fictional, internal universes that, for them, become a sort of alternate reality," Bloch said. "For example, a young rapper named Kurupt told me how the feds have tapped his phones, and how he's wanted in more states than John Gotti. A New York-area MC by the name of Nas told me that he was recently chased in his Lexus by CIA agents but managed to escape when Pablo Escobar, his business partner and passenger, shot the driver of the pursuing vehicle. These sorts of paranoid, delusional fantasies are classic warning signs of schizophrenia, and an afflicted rapper's condition can deteriorate to the point where he is completely insane in the membrane."(emphasis mine)
