The remark was not intended to be sexist. It was intended to reflect that I don't think Mayer was particularly easy to work with, that her elitist values were contrary to much of the Google culture.
(That being said: I think she is good CEO material. In fact, when she took over Yahoo! I bought stock in the company).
If you really can't imagine that it wasn't a sexist remark then I'm sorry for you: it must be hard to be so easily offended.
