I won't spend a lot of time on it but I don't think what Erykah Badu was appropriate.
Naked Erykah Badu video at Kennedy site stirs controversy
Click for article while it lasts.
It's not how she or her people didn't get the proper permits to film. It's not how she basically disrespected the site of the Kennedy assassination.
My problem with what she did is she stripped naked when there were children present. About 2:55 in the video here, you can see Erykah passes by a young boy, a very young girl and two adults I'll assume are their parents. The mother looks at Erykah and kind of pulls back on her daughter who is trying to enjoy the nice day, sightseeing. The mother then kind of pulls back on the son. She's not in good focus but it looks like the mother gives one of those "what-in-the-hell-is-going-on" looks.
Anyway, the song is just okay in my opinion. I don't know what she was really trying to say other than look how I can offend children. Good protesters don't offend or involve children. To me, that's where you lose all respect for whatever message you are trying to convey.
