effect of media consumption on males, Samantha and Bridges found an effect on body shame, though not through self-objectification as it was found in comparable studies of women. The authors conclude that the current measures of objectification were designed for women and do not measure men accurately. Another study found a negative effect on eating attitudes and body satisfaction of consumption of beauty and fitness magazines for women and men respectively but again with different mechanisms, namely self-objectification for women and internalization for men. Sexist jokes Frederick Attenborough argues that sexist jokes can be a form of sexual objectification, which reduce the butt of the joke to an object. They not only objectify women, but can also condone violence or prejudice against women. "Sexist humor—the denigration of women through humor—for instance, trivializes sex discrimination under the veil of benign amusement, thus precluding challenges or opposition that nonhumorous sexist communication would likely incur." A study of 73 male undergraduate students by Ford found that "sexist humor can promote the behavioral expression of prejudice against women amongst sexist men". According to the study, when sexism is presented in a humorous manner it is viewed as tolerable and socially acceptable: "Disparagement of women through humor 'freed' sexist participants from having to conform to the more general and more restrictive norms regarding discrimination against women." Gender identity discrimination Gender discrimination is discrimination based on actual or perceived gender identity. Gender identity is "the gender-related identity, appearance, or mannerisms or other gender-related characteristics of an individual, with or without regard to the individual's designated sex at birth". Gender discrimination is theoretically different from sexism. Whereas sexism is prejudice based on biological sex, gender discrimination specifically addresses discrimination towards gender identities, including third gender, genderqueer, and other non-binary identified people. It is especially attributed to how people are treated in the workplace, and banning discrimination on the basis of gender identity and expression has emerged as a subject of contention in the American legal system. According to a recent report by the Congressional Research Service, "although the majority of federal courts to consider the issue have concluded that discrimination on the basis of gender identity is not sex discrimination, there have been several courts that have reached the opposite conclusion". Hurst states that "[c]ourts often confuse sex, gender and sexual orientation, and confuse them in a way that results in denying the rights not only of
