Gender
Gender is the range of characteristics pertaining to, and differentiating between, masculinity and femininity. Depending on the context, these characteristics may include biological sex (i.e., the state of being male, female, or an intersex variation), sex-based social structures (i.e., gender roles), or gender identity. People who do not identify as men or women or with masculine or feminine gender pronouns are often grouped under the umbrella terms non-binary or genderqueer. Some cultures have specific gender roles that are distinct from "man" and "woman," such as the hijras of South Asia. These are often referred to as third genders.
Gender Studies
Gender studies is a field for interdisciplinary study devoted to gender identity and gendered representation as central categories of analysis. This field includes women's studies (concerning women, feminism, gender, and politics), men's studies and queer studies. Sometimes, gender studies is offered together with study of sexuality.
Law
Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. Law is a system that regulates and ensures that individuals or a community adhere to the will of the state. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent, normally in common law jurisdictions. Private individuals can create legally binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people.
Gender
As far as I'm concerned, being any gender is a drag.
Patti Smith, quoted in Levine, Martin P. (1998). Gay Macho, New York: New York University Press.
Law
As in elections, the law pretended universal rights, while securing the interests of powerful houses.
David Brin, Glory Season (1993), chapter 27.
Gender
Between a real man and a real woman there are innumerable others, some of which are significantly characterized as belonging to the intermediate sex.
