Lupe on Islam:
"Well, I was born Muslim, so Islam plays a part in my everything I do, to a certain extent. I'm not like the poster boy for Islam you know what I'm saying? So it's like I still got my flaws and stuff like that, so I don't really wear that on my sleeve. [But] I'm really with some underlying consciousness, no matter what it is that I can talk about -cocaine, or I can talk about carrying guns. I've been literally carrying guns since I was five, like four or five years old, simply because my father was in the military and he wanted to teach us how to shoot. I've been shooting AK's since I was as baby, you know? I don't like to glorify ignorance or nothing like that, but I know you need to – you can talk about it in certain aspects. You'll still get the people who don't listen unless you're talking about nonsense. Catch their ear, and then at the same time, teach them something, you know? It [also] plays on the extra curricular stuff that happens about, about being like a rapper and being in the music business like going to – all right, I don't go to clubs, I don't drink, I don't smoke, you know like my whole – the whole groupie situation is shut down."
