Even moving away from voluntarily saturating yourself, I wonder if, as Chris Rock suggested, the advent of the smartphone is destined to push stand-ups into doing 'safer' material, for fear of offending/losing the crowd, having it uploaded before it's ready and getting lynched for being racist, sexist or slanderous. I worry that he's right.
I doubt very much that Banks is a homophobe. She has worked with many gay artists and is bisexual herself. But the fact that sales of her music have risen sharply since her tweet to Perez Hilton probably suggests that she won't be admonishing the homophobic members of her fan base any time soon... We all know that freedom of speech is fundamental to any democratic society. If you want to say the word "faggot" you are free to do so, but you should also accept the consequences.
