If I understand the ask correctly, someone is looking for proof of prejudice. Here is a passage that might help:
McMichael, Lonie. Acceptable Prejudice? Fat, Rhetoric, and Social Justice. Pearlsong Press, 2013.
From Chapter 6: Is it Prejudice?
I often hear people suggest that by looking at a fat body they can tell how much a person eats, how much they exercise, and what kind of person lives in that body. People prejudge fat people. The Oxford English Dictionary defines prejudice as a ā[p]reconceived opinion not based on reason or actual experience; bias, partiality; (now) spec. unreasoned dislike, hostility, or antagonism toward, or discrimination against, a race, sex, or other class of people.ā Fat prejudice, stigma and oppression abound in our culture. Entire articles and books have been written detailing fat issues as a whole and numerous studies have been conducted detailing domination in many situations. In this chapter, I bring to light only a few of the most interesting and relevant statistics.
American society as a whole has preconceived negative attitudes ā in other words prejudice ā toward fat individuals based solely on their body size. In āConfronting and Coping with Weight Stigma,ā Puhl and Brownell summarize the perceptions of fat individuals:
Negative stereotypes include perceptions that obese people are mean, stupid, ugly, unhappy, less competent, sloppy, lazy, socially isolated, and lacking in self-discipline, motivations, and personal control.
Because of the panic around childhood āobesity,ā children experience a great deal of fat prejudice ā often experiencing pressure or teasing from the adults who are supposed to protect them. Preschool aged children already have anti-fat bias, while those with a caregiver who have anti-fat attitudes have higher levels of anti-fat bias. As many as 25% of adolescents report weight-based teasing throughout their adolescent years by their peers, and 48% report teasing by both peers and family, with obese adolescents report significantly higher incidence of teasing. Overweight adolescents who are teased experience a greater risk of disordered eating thoughts and behaviors as well as psychological problems such as anxiety, low self-esteem, depression and anger says Libbey et al. And, most disturbing of all, prejudice toward fat children and teens appears to be growing, not diminishing. A recent study by Lumeng and others has shown that fat children are six times more likely to be bullied than children who are not fat.
Fat individuals also experience stigma. Erving Goffman, a sociologist writing in the 1960s, has defined stigma as āan attribute that is deeply discrediting.ā Friedman, Ashmore and Applegate say that, for the fat individual, stigmatized experiences include the following:
Encountering physical barriers (e.g., not being able to find medical equipment in an appropriate size), people making unflattering assumptions toward the obese individual, being avoided, excluded, ignored because of weight, and receiving inappropriate comments from physicians.
Finally, fat individuals experience oppression. Merriam-Webster defines oppression as āunjust or cruel exercise of authority or power.ā As I will show in the next few paragraphs, fat individuals are denied jobs and opportunities based on their body size alone.
Body size can affect income. Being fat can reduce a white femaleās net worth significantly says Zagorsky in an article entitled āHealth and Wealth: The Late-20th Century Obesity Epidemic in the U.S.ā Puhl and Brownell found in 2001 that fewer āobeseā employees are hired into high-level positions and fewer āobeseā individuals are promoted. College students ranked āobeseā individuals as āhaving less leadership potential, as less likely to be successful, and as less likely to be employed than normal-weight candidatesā while assigning them lower starting salaries and considering them less qualified, according to a 2008 study by OāBrien, Latner, Halberstadt, Hunter, Anderson and Caputi . Interestingly enough, individuals with a BMI over 35 experienced higher levels of perceived mistreatment when they were of higher socioeconomic status, according to Carr, Jaffe, and Friendman. We can see that being fat can affect individualsā opportunities in terms of both employment and wealth.
We also cannot ignore the fact that fat prejudice is tied up with classism. A fat person is more likely to be poor and lower class than their thinner counterparts, says nutrition professor Paul Ernsburger in The Fat Studies Reader. Ernsberger argues that fatness actually causes poverty, saying that āintelligent fat people were far more likely to end up living in poverty than intelligent thin people.ā
Scholars have established that fat prejudice, stigma and oppression exist in a great quantity. This discrimination and prejudice has almost doubled between 1996 and 2006 and now rivals race and age discrimination a study by Andreyeva, Puhl and Brownell found. However, our society does not see this domination as an issue since fat people are expected to lose weight in order to overcome these concerns.
