Really? Most of us come on here to watch the videos and see what everyone thinks about the performance and their skills. I could care less about someones hair color, the way they shimmy, or if they contort their face to look like Fire Marshall Bill. In a sport that is (supposed to be) so accepting of all types of individuals and you are expected to be a bit flamboyant, some of you sure seem to be bothered by the silliest things.
If they're hitting their skills, I say shimmy away! Dye your hair bright purple! Look like the Joker! I don't care, just thrill me with a great routine and I'm happy.
