Eh, yes and no when it comes to glorifying. They were still "outlaws" and weren't held up as someone to admire necessarily. More like characters in a story really.
Half the rappers out there are "characters in a story." A good many of them are college educated, and have never seen the inside of a jailhouse.
To name a few: David Banner grad of Southern-Business, Ludacris grad Georgia State-music management, Guru grad Morehouse-Business Admin.
I'm not knocking you for your taste preferences, as to each their own, but let's not say all rappers are bad guys and all rap sends a bad message.
