From Radicals:
"I'm not saying to go out and do some stupid shit, commit crimes. What I'm trying to tell you is, do what the fuck you want. Stand for what the fuck you believe in, and don't let nobody tell you can't do what the fuck you want. I'm a fucking unicorn, and fuck anybody who say I'm not. Wolf Gang"
Just like Based God, Wiz Khalifa, and so many others, its about being yourself and doing that to the fullest extent possible. And the subtext of tyler vs. Wolf Haley represents who he is, vs. his attempts to lash out at a society that he's frustrated at. Its his teen angst being expressed through his alter ego, while he fully admits that he's just a little hispter kid shithead. Why do you think there's a therapist talking with Wolf throughout the entire album? The therapist is trying to convince tyler to calm down, be a "normal person" get a regular job or whatever and just be stable. Wolf takes over by the end, and the result is that tyler is freed from his social expectations, and becomes the counter-culture, badass, doing-literally-anything-he-wants person he dreams of being. By transforming into Wolf Haley he leaves behind the influences and pressures of parents, schools, teachers, etc, and becomes himself to the fullest extent possible. The destructive nature of his transformation also serves as a warning; his attempts to lash out at expectations and stereotypes destroy him and his friends, but its not him that causes this destruction, its an external societal motivation. Those who are different will be destroyed whether society does so, or society causes them to destroy themselves.
The guy doesn't even smoke weed, party, or do drugs. He's a musician and a really creative writer who found a niche in hip-hop by making a concept for his music.
