I know - big deal - it's pretty mild stuff. But think of it this way: There is no justification for showing anyone in the shower. The Olympic committee makes its money from TV ratings, and it appears to be using the bodies of female athletes, mostly underage teenagers, to boost ratings. (It will be interesting to see whether male divers get the same treatment - we may reach "equality" by exploiting teens of both sexes.)
The central Olympic committee is not the only group to blame. The national organizations that choose the outfits their athletes have to wear are also pretty crass. The French female gymnasts are wearing outfits that are cut so high in the leg that they're bare almost up to their belly buttons. The male beach volley ball teams were given nice, comfortable outfits: baggy tank tops and baggy shorts, while the female teams were given little two-piece bathing suits.
The commercialization of young women in sport is not the exclusive domain of the Olympics committees, of course. Young women sometimes sell themselves, which is why the top earners in women's tennis are frequently not the top seeds. One of the gymnasts I saw today was wearing light blue glitter eyeshadow that was about as tacky as anything I've seen. But it's fair game for a woman to want to capitalize on her looks, get herself noticed, vie for endorsements. It's a whole nother thing when women who just want to compete are forced to become sex objects. It's quite possible that most of them want to look sexy, but what of the female athletes who don't?
Update August 11: Yup, the boys are also being filmed in the shower. I guess I'm starting to change my mind about the shower thing. In the town where I grew up, women taking showers was a strip club favorite that was regularly advertised on the front page of the KW Record's entertainment section (with tag lines like "Our girls get wet for you"). (Kitchener-Waterloo has since got rid of most of the strip clubs, and the Record has instituted some standards in advertising.) So to me, filming women showering is pretty gross. Now that I see the boys, even though they're also wearing itty-bitty bathing suits, it takes on a different tone. The Olympics are a celebration of the body, after all, and the triumph of the mind over it; the celebration is about the body at its finest, which in most sports means the teenage body. Our society has got so creepy with the commoditization of people that I think I misinterpreted this.
