Censorship in the USA

Let's talk radio...

• 'Cocaine' was censored from the country version of Kid Rock and what's-her-name's 'Picture', but 'damn' was left in.
• In Kid Rock's 'Cowboy' they censored our 'paint his wife white'.
• In Eminem's 'Lose Yourself' they bork up the word 'whores'.
• In Eminem's 'My Name Is' they changed 'I drank a fifth of vodka dare me to drive' to 'I drank a fifth of koolaid, dare me to drive?'
• In Puff Daddy and the Family's 'All About the Benjamins' they censored a lot of stuff, including 'niggas', 'bitch', etc.

And yet on National Public Radio I have heard words 'bitch' (Nixon quote) and 'nigga' (rap lyric on Fresh Air). Bet they wouldn't shy away from saying 'cocaine' either.

(Disclaimer: Yes, I know censorship is not the proper term.)
