I love music and I love to dance... I took fitness dancing in college. Just because I love it doesn't mean I'm good at it or that I'll be on stage... but it makes me feel better... so I do it in the privacy of my own room or with my girlfriend at the gay bar when she's in town to visit XoD
If you like to do it, screw body awareness, do it! The only loser is the one who limits self because of useless people who have no education about the situation. If they laugh, that's their fault. (I know, it is hard to ignore, but easier when you're with a group that you trust ... I do not recommend doing this alone in public by any means.)
