Dichotomy, from the Greek word dikhotomos, describes something that is divided into two opposite categories. Gender Binary, the idea that men and women are two mutually exclusive and opposite sexes, is an example. This perception of gender excludes individuals who identify themselves as non-binary, neither woman nor man. A dichotomous world also creates hierarchies between both the sexes.
This can be illustrated by means of the gender system theory, according to which each society creates and maintains a system in which women and men are assigned different roles and positions. The gender system is based on two principles: separation of the sexes and establishing hierarchy. A gender-segregated labour market, women’s underrepresentation in the job sector, and undermining women’s work are examples of gender system. Ecofeminist and postcolonial researchers argue that dichotomies legitimise domination and oppression in different levels.
