I've gotten that - "YOU liked that movie?" But the people I've gotten it from are a couple of the gay men I work with. Fortunately I work in a fairly liberal, relatively gay-friendly environment, so there aren't too many people around who are openly homophobic. Lucky for them, because I've become a real pain in the ass about homophobia in any form lately.
All the folks I've worked with and known for years know all about my little movie (and otherwise) obsessions. I'm one of those people who isn't good at hiding whole parts of myself from others - in fact I don't even try. Maybe they whisper behind my back about what a colossal flake I am. OK, probably they do. But that doesn't stop them from coming and asking me whether I recommend a movie they're thinking about seeing or what I thought of one they just saw.
As we've talked about before, I've had some vast disappointments in terms of friends I was sure would be deeply moved by this movie who just... weren't. But I've had some happy surprises, too. One was in the form of a longtime friend - a married straight guy who had said some marginally homophobic things in the past and had joked that he "wouldn't ever be seeing 'that' movie." His wife convinced him to and they both loved it. I think he thought I was a little (lot?) off for a long time after it came out and I was so ga-ga over it, and then so infuriated when it didn't win the Oscar. He even tried to sugar-coat its loss, not having seen either it or "Crash." Pissed me off. Then he saw "Crash." And said, "Ew." Then he saw "Brokeback," which I truly never thought would happen, and he said, "You're right. They were robbed." Sounds trivial, but I can't tell you how happy his saying that made me. And I've noticed he doesn't say little homophobic things anymore - at least not around me. What I like to hope most of all is that it changed the way he thinks. I believe it did.
Getting back to the matter at hand, I think there are closet fans. I think he's one of them. And every now and then someone (not me, I swear!) will bring up the movie in mixed company, and someone I didn't know had seen it will say, "Yeah, that was a GREAT movie." I don't pursue it with them, usually, but I wonder if they've secretly seen it "more than once" and secretly still mourn Jack.
