Witches jumpin' ship?

If America, as a society, and Hollywood, as a sort-of microcosm of that society, have come so far that a song called "It's Hard Out Here for a Pimp" can win an Oscar, why is it that we still have to censor the word "bitches" when said song is performed on TV at 10:30 on a Sunday night, especially when such censorship results in the phrase "there's a whole lotta witches jumpin' ship"?

It's March. Anyone else feeling mad?
