Gender binary

The gender binary, also referred to as gender binarism (sometimes shortened to just binarism), is the classification of sex and gender into two distinct, opposite and disconnected forms of masculine and feminine. Gender binary is one general type of a gender system. Gender binary is one of the core principles of genderism; it describes a social boundary that discourages people from crossing or mixing gender roles, and from identifying with more than two forms of gender expression. Sometimes in this binary model, "sex", "gender" and "sexuality" are assumed by default to align. For example, when a male is born, gender binarism assumes the male will be masculine in appearance, character traits, and behavior, including having a heterosexual attraction to females. Gender binarism is only one belief regarding gender. Other groups believe that sex and gender can differ in individuals, while still disagreeing with the idea that gender is non-binary.

The term gender binary describes the system in which a society splits its members into one of two sets of gender roles, gender identities and attributes based on reproductive organs. In the case of people born with organs that fall outside this system (intersex people), enforcement of the binary usually includes coercive surgical gender reassignment. Gender roles are a major aspect of the gender binary. Gender roles shape and constrain an individual's life experiences, impacting aspects of self-expression ranging from clothing choices to occupation. Traditional gender roles continue to be enforced by the media, religion and educational, political and other cultural and social systems. Major religions such as Islam and Catholicism, in particular, act as authorities for gender roles. Islam, for example, teaches that mothers are the primary care givers to their children and Catholics only allow cisgender men to serve as their priests.
