As I said and Hilbert said in other places, this is about trends and tendencies. Not specific cases. As this discussion is about why women don't pursue careers in computer science as often as men, it is appropriate to speak in generalities. The quotes you're picking sound bad, but they're not. "There can be a reason for a girl in college to take some courses in computer science: Look for a husband!" He's not saying the only reason any girl should ever take computer science classes is to find a husband. He's saying that a girl following typical gender roles will actually use that reason as opposed to the other good reasons for doing so. "Further, what on earth are you talking about when you say that his post is in line with expert opinions on the subject?" Look into the subject of moral development. There are conflicting views on the subject, but at least one of the views (promoted by Carol Gilligan) is very similar to what Hilbert has been saying.
