Utilitarianism and homosexuality, again

I've long been one of the top Google results for the utilitarian view of homosexuality, but I discovered today that I'm losing out in some permutations of the search. One of the new top results is this post slamming homosexuality along with a long list of other deviations from 1950s sexual mores, from what I can only conclude is a Colbert-esque parody of a conservative blog. It includes such prize arguments as: single people go to restaurants more often, so cohabitation is bad for the economy. The author's twisted visions of sex and utilitarianism are an amusing break from the usual claims about unnaturalness or "because I said so."
