The left wants you to add women to your team to make the world a better place.
Ever since I was a kid I tended to hang out with the girls in the neighborhood; I enjoy female company. But hiring should be about fairness. If you tend to hire from the top 25% of the Stanford or Berkeley graduating classes and those sets are 30% female, then by golly, why aren't 30% of your hires female? But if that's not the case, and you're giving more slots to women than there are precentage-wise in the pool of candidates, you're treating someone unfairly who has worked very hard to get where he is.
