So I'm guessing you've probably already seen or heard about the whole "too many sugar plums" controversy? Alastair Macaulay has managed to bring up weight in ballet again (as if most of the ballet dancers in the studio don't confront that every day). Jennifer Ringer, the Sugar Plum in question, was interviewed on Today Show (most interesting how she says NYCB has a variety of body types...). And Mr. Macaulay's response in print was basically that he didn't make the ridiculous body image standards of the ballet world, he just enforces them.
In addition to the body image issue that touches off women's personal reactions, the fact that the Black Swan ballet movie has just come out means it's even more appealing to mainstream media. No one is interviewing "downtown dancers" in the wake of another of Mr. Macaulay's online "controversies"--the fact that as the NY Times dance critic, he really only has an interest in classical forms, and a handful of the more musical of contemporary choreographers. I guess that story doesn't have as wide an appeal of course, it's pretty much only offends the downtown NY dancers (and their audiences) that he doesn't pay them any attention.
But back to the weight issue, who hasn't had body issues of one kind or another (if you're somehow lucky enough not to have weight as one of those) that come up as a dancer? As everyone points out, your body is your tool for making the art and so there you are. And in ballet especially, the "facility" required for professional dance is really freakishly rare. I've wondered sometimes what's worse, the old school communist style recruiting where kids were chosen specifically for their "facility" and made to dance whether they wanted to or not, or the democratic every girl in a pink tutu version, where they let you dance your heart out as a kid only to have it crushed by the realities of your genetics as you grow up.
