I love this song, but I don't think she's talking about perfection being wrong... and I hope bulimia could never be misconstrued as perfection. I didn't view the video in its entirety, but in the full version of the song, there is a part where you hear sounds like a girl is vomiting, and she almost croaks out, "I just wanna be thin." Pink's song is not merely a chick-bashing ballad; rather, it seems a melodic diatribe condemning the stupid things girls do to please men, or to please society, such as deteriorating their esophogial tissues simply to be thin. The bulimia part of the song was not included in the radio edits, and I think this is a travesty... with the prevalence of anorexia and bulimia among teenage and 20-something girls, it would be nice to hear such a blatant condemnation of such behavior from a teen role model like Pink.
Just my opinion... and maybe a little too close to home... my best friend in high school, who consequently I was in love with, was anorexic and bulimic.
