I guess this is an issue that I have some perspective on...
I'm carrying more weight than I ought to...having a very shoulder-y and generally stocky/muscular build kind of carries it a lot better than it would be in a lot of cases...though yeah that said I draw the line between myself and those perceived as "fat" which IMO is just the general term for obese...kind of a few steps away from what I am.
Er, tank-ish perhaps?
Essentially my diet's good just my lifestyle/excersize I need to work on, part of the reason I got my dog.

Though I'm not sure if I'd be in the category you're talking about...I would imagine you're thinking about BIG FAT people, like, all fat no muscle, men with bigger tits than women, sweaty fat people that don't even fit into the standard "x" sizes?
Yeah well...I have to say I think that it's a little off-putting, like, why haven't they done something about it before it's got quite THAT bad...I look at myself now and acknowledge I'm a work in progress that needs improvement, then when I see a person bigger, twice my size, gut hanging over their crotch, arms that look like pork roasts, never NOT out of breath...I yeah, feel a little bit like they're either lazy, or just stupid to not even have self preservation to the point that it'd see them much past the half way mark in most peoples lives.
I'd probably deny them a job that had to do with physical exertion like security patrol, manual labour, or dealing directly with the public as obviously it's something that they're unaccustomed to in their lifestyle outside of work, and often they'll meet with persecution on sight from "customers".
Though, if it were a job where they could just sit on their asses...something like a manufacturing line, or office work, data entry, call centre stuff, there's a lot of jobs they'd be capable of doing.

That said, I think you're assumption that most fat people eat lots/too much/when bored or otherwise substitutionally is incorrect...most cases that I've known about personally stem from lack of exercise more than anything, and not so much amounts of food consumed, more the types of food...but again this is about lack of activity, the "easy" choice is often worse for you.

I have to say though I think they're discriminated plenty...I mean hell I'm an overweight guy and I myself have this perception of them though I'm perhaps a little more accepting of them, hey that might just be because they make me feel better about myself, or maybe I just think about what their life would be like...if you take a look at them, not many of them even seem to have many friends, they tend to not be taken seriously by the opposite sex so if they ARE in a group situation they'll be the perpetually single "fat" person of the group.
(In my case...I've actually SEEN people avoid me because of my overall size PLUS weight, it's like they think they're going to get hurt? Though I don't cop nearly as much as I would if I was JUST "fat")
It may be their fault through incorrect diet or lack of action, but that doesn't mean that their life doesn't suck...I would say that in the workplace and for job prospects you'll find they're already pretty shunted in a lot of cases.
