I know some groups are worried about "freaking," that genteel style of dancing involving dance partners sexually grinding against each other. China apparently has a similar problem -- kids holding hands while dancing. BBC News has the story. Interestingly, the Chinese government is promoting dance as a way for increasingly overweight kids to get exercise, but some are worried.

Some parents had expressed fears that if boys and girls danced hand in hand they might fall in love and put their studies at risk.

I wonder if the Chinese might be receptive to square dancing. It seems less scandalous than the waltz.
