I have to say, though, that I actually got a sexist feel from the article as a whole stronger than I did a homophobic feel.

I do think that there's a strong element of 'Marriage is a tool for controlling women, and if it doesn't serve the purpose of binding women to men, it's worthless at best and dangerous at worst' to a lot of anti-gay-marriage rhetoric, and I would not be surprised to catch a strong whiff of it from Card.

I used to love his books, but his female characters were often the tamers and gentlers of men, but easily led astray by bad men, who needed a strong male hand to keep them in line. Ick.
