Disagree with that. Midnight Cowboy, Philadelphia, My Own Private Idaho, Kiss Kiss Bang Bang, Dog Day Afternoon, The Birdcage, In & Out, Gods and Monsters, I Love You Philip Morris, Milk, A Single Man, The Adventures of Priscilla, Queen of the Desert, Longtime Companion, Torch Song Trilogy, To Wong Foo, Thanks for Everything! Julie Newmar, Jeffrey, Parting Glances, Velvet Goldmine, Love! Valour! Compassion!, The Sum of Us, The Broken Hearts Club, and many more. Those are just the ones I can think of off the top of my head. Probably missing some other obvious ones.
I think her point was that most homophobes, when given the choice, will watch a movie like black swan and say; "Oh hey now, we got two chicks doing the nasty, this is hot!"
Where as the same homophobe will possibly see a movie like the ones you listed where two guys get it on and say; "Oh jeez, GROSS!!! Give me a break I'm so tired of Hollywood trying to force me to accept the gay lifestyle! Give it a rest!"
