It is ok to make fun of fat people. Fat people can be judged in public without the person passing judgment feeling badly about it. Fat people can eat healthy in public and receive judgement. Fat people can eat junk food in public and receive judgement. If a fat person is handicapped, Americans assume it is because they are fat. If a fat person has any health problems, doctors assume it is because they are fat. Clothing companies do not make clothes for fat people. Seats in public places are not designed for fat people. Fat people can't ride roller coasters. Fat people are supposed to believe that they are stupid and lazy. Fat people are supposed to believe they need to diet.
