How do we measure equality when our society's definitions of "male" and "female" leave out much of the population? While significant strides have been made on behalf of women's, gay and lesbian rights, there is still a large division between the law and daily reality for LGBTQIA and female-identified individuals. The practices, media outlets and institutions that privilege heterosexuality and traditional gender roles as "natural" need a closer examination. Gender & Sexuality For Beginners considers the limitations of biology in defining gender. Questioning gender and sex as both categories and forms of compulsory identification, it examines the issues in the historical and contemporary construction, and perpetuation of gender roles. This book interweaves neurobiology, psychology, feminist, queer and trans theory, as well as historical gay and lesbian activism to offer new perspectives on gender inequality and how the system oppresses us all.
