Let me answer my own question: because he is an appallingly freakish idiot, and always a reliable source for the most amazingly inane claims. Don't worry, that link takes you to Mark Chu-Carroll's evisceration of his latest insane rant, that women are intellectual inferiors who can't teach biology or calculus and are incapable of practicing computer science or art. Vox Day. Can he do any of those things? I think not.

By the way, my wife is director of institutional research at a local college, and my daughter is a computer science major. Women outnumber men in our computer science program and have parity in our biology discipline. It's amazing how they do those things and know more than I do in their fields with such inferior brains.
