He thinks he is, so he is. Being a gangsta is all about a lack of respect for humanity, which I believe he has in spades.
Revis Christ, do I have to hold your hand on this one? It's the little circle in the big circle thing. All gangstas have a lack of respect for humanity. All those who have a lack of respect for humanity are not necessarily gangstas.
I think your definition of gangsta is still a little off. When he's dealing rocks and shaking down businesses for protection money, I'll accept your assessment.
