It's the people involved, watching or otherwise, that make it perverse or not IMO. The idea that this video of two little girls dancing (even were they naked) is perverse is not an objective fact. It is something which arises out of modern common opinion. Most little kids, unhindered, would dance around naked if allowed and think nothing of it. Does that make them perverts or bad or that anything about them dancing or being naked is bad? No. It is the adults, conscious of sexuality as they are, that turn it into something 'gross'.  It is also because we, as adults, KNOW that other adults are capable of this that we try to shelter our children from it by prohibiting what they do.

That said, I do not condone dressing little girls (or boys provocatively). There is no reeason for it and for the above stated reasons it is safest for the children. Children should also be taught to dress and behave conservatively from a young age... IMO... because it will help them function later in life as adults as well. I say this despite having mixed feelings about limiting children's ability to express themselves naturally. I feel it is wrong... for anyone to be inhibited from expressing themselves but... in the grand scheme of things it is a necessary evil. It keeps our society functional and solvent.

Yeah this is probably wrong to show to anyone although I understand that Dance is a way o xpress sexuality,8 year old girls shuldnt have sexuality so th shldt be d s kinda sh* but with certain role models I can understand why the "2003" kids are so screwed up
