Has anyone ever seen the movie "Rize" ? It's a documentary on urban street dancing that came out of the hip hop movement. Very powerful, and the dancing is phenomenal. But it does raise some of the same questions because some of the moves are interpreted as very sexy, and they are done by girls as young as 5. Of course one difference is that the dancing is done in large groups with nobody touching each other. Another is that all the people are fully dressed.
Anyway, just thought I'd add that to the conversation because as Katie mentioned, this was an urban dance competition.
