It's a flawed argument. In a group of male programmers, fully half of them are below average (yes, I'm sure). Should the less accomplished 50% be subject to ridicule as intellectually inferior? No, they should be given equality of opportunity, and let the cards fall there they may.
All women want is the same equality of opportunity that every male programmer gets without question.

Quote: "... a tendency of people to favor information that confirms their beliefs or hypotheses."
