Yes, but if you look closely, we are actually showing our disbelief toward obeasts only, not fats. There is a certain number of studies in social psychology in progress (in France) interested in obesity as a stigma and why normal people feel this way toward this group. I can tell you that the answers they get from the general public is pretty straightforward and unapologetic (deep-rooted disgust, feeling that they are lazy, etc.). I'm kinda afraid when I see the researcher saying that we have to change this perception. Mostly so that employers become less reluctant in hiring them. But as I said above, 99% of the obese people I meet have issues and are not responsible of themselves. So, when I see one that is supposedly mentally sound I can't help but wonder what is wrong with it for being in that state. I kind of went off topic here, sorry. As for McDonald's, the consensus in my circle is that it is way too expensive for junk food of this quality. I don't think it's doing too well this days.
