Homophobia and hip-hop are in the news once again. Advocacy group GLAAD is criticizing Azealia Banks for calling Perez Hilton a homophobic slur over the weekend. After the openly gay celebrity blogger backed rapper Angel Haze in her feud with Azealia, the latter called Hilton a “messy fa---t.” Banks, who is bisexual, later tried to clarify her remarks: "A f----t is not a homosexual male. A f----t is any male who acts like a female. There's a BIG difference." GLAAD, however, wasn’t convinced: “Banks’ claim that the word "fa---t" doesn’t mean a gay male is not true,” a representative wrote on the organization’s website. “Undoubtedly there are gay kids who follow her on Twitter who hear this word in an entirely different context. This word is used almost universally by bullies, often as part of a larger verbal or physical assault. This word hurts those kids, no matter what Banks meant by it.” But this isn’t the first time that GLAAD has clashed with the music world.
