Critical Gender Theory can be divided up into several branches through which these questions (presented in the intro) can be answered in a more focused outlook. There is the Feminist Theory, referring to the analysis of literature and not the equal rights movement, which criticizes the dualism of male/female roles and focuses on the key ideas of equality, difference, and what that difference means in society.
Queer Theory rejects the idea of essential gender or fixed identity and also questions equality and difference when dealing with homosexuality; often critics seek to reveal the author’s sexuality based on his/her works.
Essentialist Theory advocates the pure biology of gender, gender roles, and sexuality, citing hormonal and physiological differences that account for the deep chasm of separation between men and women. A spin off of Essentialist theory is the idea of Heteronormativity or that heterosexuality is institutionalized and integrated into global society – for example the common sight of men's and women's bathrooms, yet the extremely rare sight of spaces for the transgendered or intersex.
