Where does sexy end and sexism begin? I too am against sexism (who isn't?), but most Americans appear to find women in limited amounts of clothing sexy; take a look at most women's magazines in the grocery store next time you're there (or, better yet, look through a bunch of Cosmos at some point: someone suggested I do it, and I found the experience highly educational). Sexism in tech and the workplace are real problems, but I don't think a slide with a woman in underwear is a good example.
Comparisons between the U.S. and France are often dubious, but reading Elaine Sciolino's La Seduction: How the French Play the Game of Life made me rethink some of the issues Koll describes. Sciolino writes, for example:
The game of the sexes also extends deep into the workplace. In the United States, the mildest playfulness during business hours and in a business setting is forbidden; in France, it is encouraged. In American corporations, men are told routinely that they cross the line when they compliment a female employee on the color of her dress or the style of her hair. In France, flirtation is part of the job.
(I wrote more about the book here: http://jseliger.wordpress.com/2011/08/09/la-seduction-how-th...).
And her experiences in the French workplace appear to be mostly good. It might be that the U.S. and France are too different to compare, but I also don't think that the asexual approach implicitly endorsed here is right or even practical.
