Me thinks your problem isn't fat people per se, but the abhorrent manner of dress common to many lower-middle class white Americans.

My local Target is VERY hispanic, and the people tend to be short and chubby. (The clothing matches them). But they take care of themselves - the mexican women haven't yet gotten the idea that "big = bad," so they wear pretty clothes and do their hair nice and generally look aesthetically pleasing. Same for the guys.

But head up the interstate an hour to the exurban white Target and holy shit. Sweatpants, crocs, and the occasional all-american skinny ass blonde in her boyfriend's jacked up F-150.

Fat stigma CREATES ugly fat people, by encouraging fat people to give up on trying to look nice.
