There's two answers to this, that both have a bit more nuance than I expect HN to be okay with.
One is that the AWB wasn't a racist provision of the overall bill. The gun control measure was not rooted in racism.
The second is that the bill as a whole wasn't "rooted" in racism. It certainly was a bad bill that had terrible consequences, and we should undue a lot of the damage it did, but the intent of the bill was, in part, to help the black community (and it had support from many people in the black community at the time). Horribly misguided in hindsight though.
The crime bill was designed to stop the "super predators" (to quote two democrat presidential candidates). It was a racist depiction of black men. It included a provision to outlaw scary black guns. You can't really divorce the two and pretend they're not related.
