recent criticisms of Judith Butler's theories critique her writing for reinforcing the very conventional dichotomies of gender. Social assignment and gender fluidity According to gender theorist Kate Bornstein, gender can have ambiguity and fluidity. There are two contrasting ideas regarding the definition of gender, and the intersection of both of them is definable as below: The World Health Organization defines gender as "the characteristics of women, men, girls and boys that are socially constructed". The beliefs, values and attitude taken up and exhibited by them is as per the agreeable norms of the society and the personal opinions of the person is not taken into the primary consideration of assignment of gender and imposition of gender roles as per the assigned gender. The assignment of gender involves taking into account the physiological and biological attributes assigned by nature followed by the imposition of the socially constructed conduct. Gender is a term used to exemplify the attributes that a society or culture constitutes as "masculine" or "feminine". Although a person's sex as male or female stands as a biological fact that is identical in any culture, what that specific sex means in reference to a person's gender role as a man or a woman in society varies cross-culturally according to what things are considered to be masculine or feminine. These roles are learned from various, intersecting sources such as parental influences, the socialization a child receives in school, and what is portrayed in the local media. Learning gender roles starts from birth and includes seemingly simple things like what color outfits a baby is clothed in or what toys they are given to play with. However, a person's gender does not always align with what has been assigned at birth. Factors other than learned behaviors play a role in the development of gender. Social categories Sexologist John Money coined the term gender role in 1955. The term gender role is defined as the actions or responses that may reveal their status as boy, man, girl or woman, respectively. Elements surrounding gender roles include clothing, speech patterns, movement, occupations, and other factors not limited to biological sex. In contrast to taxonomic approaches, some feminist philosophers have argued that gender "is a vast orchestration of subtle mediations between oneself and others", rather than a "private cause behind manifest behaviours".
