That's a really terrible rebuttal. I was struck by the fact that Sailer seems to think it's impossible to be both aggressive and "cultivated." In my experience, these two traits are almost uncorrelated.

Also, his argument (insinuation, really) that female consumer spending in the US was a driving force of the sub-prime crisis completely is completely tangential to Lewis's argument, which is about male financial workers. (To my mind, both arguments seem unlikely and rather sexist. I'd like to think Sailer is being ironic, but no, he's not.)
