We hear rappers every day who glorify murder, rape, mayhem, drug-dealing, racism, predation, and prostitution, who routinely refer to women as whores and female canines, and who espouse violence as a hobby. The same people who take umbrage at these girls no doubt celebrate the unique "earthiness" of the (c)rap experience, and pretend to enjoy the jungle sounds of drumbeats, hooting, and gorilla-like bravado.
Nope, no double standard here.
