There are a few artists that have taken up controversial topics, but in truth not enough. I think many artists saw what happened to the Dixie Chicks and want to avoid angering their audiences, audiences made up of Conservatives/republicans who think America is God's gift to the rest of the world and who can do no wrong.

That being said, Keith Urban's song, Female, is a good example of how artists have poetically brought awareness to societal issues without angering the masses.
