Mac Miller and ScHoolboy Q N-word joke

Okay, so here's the deal, smooth brain. Back in the day, Mac Miller, a white rapper, made a joke about writing ScHoolboy Q's album. ScHoolboy Q, who is black, came back with a funny reply, pretending that meant Mac Miller used the N-word because ScHoolboy Q uses it in his raps. The whole thing is just a silly back-and-forth between friends, but then the comments section goes full conspiracy mode, debating if Mac Miller actually used slurs in his other songs. You probably think this is super deep, but really, it's just people overanalyzing a simple joke from 2014.
