My concern is I felt like the arc of the episode had the man in question consider the possibility that he was attracted to a fat woman, try this one for size, and conclude that nope, he's not attracted to the fat women physically, just emotionally. Everytime we hear him pondering his feelings, he is weighing being physically attracted or emotionally attracted, as if this were sort of binary decision. And the turning point for him comes when he stops weighing the two options and commits to being attracted emotionally. This kind of concerns me as a message.
Mind you, the idea that fat attraction is bad is, at most, subtext, so things could have gone much worse. And genuine romantic interest in a fat partner is a pretty radical thing for TV regardless of physical attraction. Still, I think its fair to be sensitive to how attraction to fat partners gets portrayed. While subtext, I got a strong sense that the character was being chided for expressing physical desire for a fat person. Every time he tried to convey that, he gets slapped down. Granted, his expressions were pretty uniformly artless, but its not like the resolution was to express the desire better. It was to not express the desire at all. So, we only every see expression of fat admiration as something clumsy, blunt, and more than a little objectifying. Except, this has a powerfully stigmatizing effect by implying that there is something necessarily wrong about being attracted to a fat person.
There is a real problem in how our culture tends to depict fat attraction. Fat characters are often left with a binary choice. Be objectified by someone who desires you or enjoy the righteous tolerance of someone who'll love you "in spite of" your body. Which, to me, sounds like two shitty choices but always plays out as good vs. bad. And guess which side gets to be good. Fat attraction is a deviation. Something othered. This doesn't just impact fat admirers, though. Indeed, the brunt of this kind of perspective is felt by the fat people since it their body being othered. Their body that is stigmatized as deviant. The admirer is shamed for how they relate to fat bodies. The fat body is the point of difference.
The truth, I'd suggest, leaves both of those binary choices as being really lousy. Better options would be someone whose physical desire was just a part of what drew them to a specific fat partner, or a person who doesn't identify with any specific physical desire who can still incorporate physical attraction into their relationship with a fat partner. Those two scenarios are the cause of happy endings. Not the partner only interested in one's fat body or the one who tries to disassociate one's physical presence with their emotional engagement.
While Glee definitely had a subtext of showing the fat attraction to be foolish, it still wasn't the text of the show and there is nothing to contradict either non-binary scenario. I'd hope that he can recognize that he does desire fat partners, but that he's looking for more than a body, mostly because fictional fat admiration is pretty rare and it'd be great to see better examples of it.
Which got me thinking about other examples. One showed up tonight on the new Matthew Perry sitcom Mr. Sunshine. A young, conventionally attractive female references an as yet unseen character as "gorgeous" in a fairly breathless delivery. When the character is revealed as the identifiably fat Nate Torrence, its obviously played as a gag of misplaced expectations. THIS is gorgeous? Doesn't help that she's already been established as possibly mentally unstable, meaning her attraction might not be meant as a quirk but as a "symptom".
The quirk aspect reminded me of Dr. (Jo) Mahoney, the late addition to the cast of Scrubs. She's established as being interested in fat men, but this attraction is immediately regarded as necessarily suspect. It's "explained" as enjoying their insecurity and desire to please her. This actually worries me about Glee, too, as it often seemed to be trying to justify the attraction to a fat woman. Though with a more positive justification ("She's confident!"), I don't like the idea that wanting to be with fat partners always needs to be justified. Frankly, a lot of fat admirers themselves do this, deluding themselves into thinking fat women are just better people and not just fatter people. At any rate, she also had a totally meaningless fat attraction since she never really acted on it and entered a relationship with a thin male as soon as the plot demanded it.
Something also seen on "American Dad" where the CIA chief voiced by Patrick Stewart declares an interest in fat women to establish him as being a deviant, and then quickly forgotten about it. Less quickly forgotten was Debbie, the fat girlfriend written for Steve, the son on the show. Oh, it got forgotten about, but briefly it was actually a pretty decent way to show a character who isn't specifically interested in fat partners going beyond "in spite of" in their attraction. Steve is fully attracted to Debbie even if her body was not relevant to that. He wasn't shown as martyring himself and his interest was actually treated very respectfully. When they broke up several episodes later, her size was a total non-issue. Shame it was introduced and dispensed with so quickly.
Most of the time on TV, fat characters are only allowed love "in spite of" being fat and this is routinely seen as a good thing. Having someone "look past" one's body is a display of extreme nobility in this world. I remember several shows when I was a kid introducing a fat girl for a male lead to learn to woo in order to be a better person. And they never even had to do anything about it after the episode, either, so win-win. It was a textbook example of the lionization of "despite". If someone actually was into fat partners, they were always a deviant and more than a couple times portrayed as necessarily a feederist with the implication that desire for fat partners and feederist interests were one and the same. This is a backdrop that gives me a lot of room for caution with Glee's still being written treatment of the subject. I could see them going in several different directions here. Some good, some bad. I'm hoping to go for something really radical and let a main character be genuinely attracted to fat partners, but I'm apprehensive that he'll be another person just learning a lesson by dating fat partners.
