Whole lot of mixed signals coming from this video and the Chandelier video. Given how our culture eroticses nudity, having dancers in skin tight flesh coloured leotards is bound to come across to many as erotic. (NOT pornographic, using erotic intentionally here) We also use it to denote ultimate defenselessness, or the ultimate trust/intimacy, but the primary way our culture deals with nudity is eroticism. Dance is also eroticised, to a much lesser degree.
You put the two of them together and there will be a huge segment of the population who will find the combination to be erotic.
Then you make the female dancer a pre-teen girl... and that's bound to cause a huge problem for many people. Simulated nudity: Erotic. Dancing: Erotic. Pre-teen girl: NOT EROTIC. NOT EROTIC. So how do you reconcile the eroticism that is implied (among other things - trust, defenslessness, intimacy, etc.) with simulated nudity and dancing?
Now, add to that how we are subtly (and not so subtly) sexualizing our children. I walked into a Childrens Place - a Canadian kids clothing store - and found some pretty short skirts that were labelled as 3T. Meaning for 3 year olds, where the skirt would come to about her upper thigh. There were bikini's for 4 year olds, and midriff baring shirts for girls of all ages. And these were fairly conservative articles compared to some of the stuff I saw at the GAP and other more famous children's stores. And the models were posed in ways very similar to adult models - ways we're supposed to find alluring in the models.
So, you've got the eroticism of (simulated) nudity, the eroticism of dancing, the confused sexualization of pre-teen girls in the society this video is aimed at... yeah. Trouble.
For the record I don't believe there is any intentional sexual innuendos in either video, where they are trying to say "We want you to want to fuck this underage girl." or "We want you to get a boner from watching what this underage girl does." Still, it's not easy to look past my cultural upbringing to see something else in there, and for people who have a vested interest in NOT seeing past it...
