1) I have to agree with those who said I don't think this girl is a racist. 2) To me the line seems like it's supposed to sort of "turn things on their head". Like it's not "slavemaster" but slave ... master - like "you thought i was the slave but I have turned the tables!" Like a Spartacus thing, where the oppressed rise up, etc. 3) It was a poorly chosen line, but probably naive. It doesn't seem like she is running around using the n-word like some of these other white rappers right now, which I think is in incredibly poor taste, but apparently endorsed (at least tacitly) by the likes of Odd Future, Gucci Mane and others. 4) Agree that a resurgence of a Lauryn Hill type era would be a very good thing.
