Oh, don't get me wrong, there was a fair bit of sexism in that performance, in the sense that whoever wrote it clearly has a very specific idea of what his audience is like: socially inept males. You know, developers. I was just too busy being offended as a developer being faced with proof of what sales people think of us to consider being offended as a woman, but the sexism is definitely there and should be addressed.
Some of the details I've heard described as sexist, though - like how the dancers are apparently "scantily clad" - seem to be more the result of mob rage than any form of rational thought.
