I'd hardly describe Advise and Consent as a pro-gay film--it makes homosexuality seem creepy and deviant and it depicts a gay bar, to paraphrase Pauline Kael, as one of the Seven Circles of Hell (any pick-up joint is, in fact, a Circle of Hell, but I doubt that Otto Preminger and his colleagues would have gotten so wracked up over a singles bar). It is true, of course, that liberals were as prejudiced against homosexuals in general as conservatives, and the Hard Left thought of homosexuality as some sort of Capitalist Disease (think of the novel and the film The Conformist).
