Is obesity the last remaining socially acceptable prejudice?
As a social psychologist, the evidence that prejudices of all sorts are alive and thriving is overwhelming. Among those prejudices are prejudices against the obese. Is this the last remaining socially acceptable prejudice? I think the evidence, again, is no. MariaMaria's example of smokers is one, but is you view prejudice as a
negative attitude, which is not necessarily followed up by behaviors, I think there are all kinds of groups for whom it is acceptable to have a prejudice. And especially when the "affliction" is considered "within their control".

It has the ring of truth to me, but maybe I am hearing a cracked bell. Or maybe I am hearing what I want to hear.
As a person who tries to teach her students how to evaluate evidence, I think this is an excellent question, and one I think we will be discussing further. I've been thinking a lot about it, too.
People keep coming back to how "statistics can be manipulated". I think it's more appropriate to say that research studies can be interpreted differently.
I think a lot of the research evidence is compelling, but we all have to remember the story isn't complete.
One of the questions I tell my students to ask when they evaluate research is "Who are the participants?" This is important because research done with one group of people does not necessarily generalize beyond that group. For example, as a former morbidly obese person, it seems that a lot of the research has been done on people who were obese, but not morbidly obese. To what extent does the research apply to the 2nd group? We don't know.
A second important question to ask is how did the researchers manipulate or measure their variables? Are there groups or ways of measuring that are left out? For instance, some people have already noted that most of the research used BMI as a measurement of obesity, yet we know that this is not necessarily the best measure of health, etc. What would happen if they looked at body fat % instead?
Also, little of the research seemed to examine the role of weight lifting, or how much muscle mass had -- does that protect the "reduced obese" from regaining weight? We don't know yet.
It helps to think of the research as evolving. We've asked some questions, and to the extent that the evidence from multiple studies done on multiple groups with multiple measures agree with each other, the stronger that evidence is. However, there are further questions to be asked which may change the conclusions we can draw.
This is how science progresses, but it can be distressing when we just want answers.
