http://www.objectivistcenter.org/objectivism/faqs/dmoskovitz_faq-moral-homosexual.asp "While Ayn Rand did consider homosexuality to be immoral, this was only her personal view."
"The few times Ayn Rand spoke publicly about homosexuality, her remarks were disparaging. She said that homosexuality is a manifestation of psychological "flaws, corruptions, errors, [and] unfortunate premises" and that it is both "immoral" and "disgusting" ("The Moratorium on Brains," Ford Hall Forum Lecture [Boston, 1971])."
The majority of that link is supportive of the objectivist view that homosexuality isn't immoral, but the sections quoted above are what I based my comments on. This month's issue of Liberty magazine has an article on the same subject.
