"The song was written for a specific person in the show, and frankly, such women aren't extinct outside the show. "
I have often made this point in defending FLOWER DRUM SONG. One time was at a screening of the movie version that was held around the time of the production of the Broadway revival, which featured a major rewrite of the script that many people considered equally if not even more riddled with stereotypes than the original.
The other major female characters in the show -- Mei -Li, Helen Chao, Madam Liang -- are NOTHING AT ALL like Linda Low. Also, the Linda character is quite similar in several respects to at least a few of the characters in SEX AND THE CITY (for example). What I said during the discussion following the screening was that I think people who have a problem with "I Enjoy Being a Girl" have a problem with it only or mostly because the lyrics were written by a white man. (With SEX AND THE CITY, the situation was a little more complicated, because the show was created by a male but the writing and directing staff featured a mix of women and men.)
