Teoria queer (Queer theory)

La Teoría Queer (< inglés queer ['raro', utilizado durante mucho tiempo como eufemismo para nombrar a los homosexuales]) es una teoría sobre el género que afirma que la orientación sexual y la identidad sexual o de género de las personas son el resultado de una construcción social y que, por lo tanto, no existen papeles sexuales esencial o biológicamente inscritos en la naturaleza humana, sino formas socialmente variables de desempeñar uno o varios papeles sexuales.

Queer theory is an anti-essentialist theory about sex and gender (and often other aspects of identity, especially race) within the larger field of Queer studies. It proposes that one's sexual identity and one's gender identity are partly or wholly socially constructed, and therefore individuals cannot be described using broad terms like "homosexual," "heterosexual," "man," or "woman." It challenges the common practice of compartmentalizing the description of a person to fit into one particular category.
In particular, it questions the use of socially assigned categories based on the division between those who share some habit or lifestyle and those who do not. Instead, queer theorists support the complicating of all identity categories and groups.
