This document provides an overview of queer identity and queer theory. It defines queer as referring to anything that opposes normalcy or dominance. Queer theory emerged from fields like women's and gender studies and critiques fixed categorizations of gender and sexuality. The document discusses how queer theory challenges notions of straight as normal and explores how new media and the internet have provided new contexts for exploring queer identities beyond the gender binary. It also notes how platforms like Facebook still rely on discrete categories of gender and sexuality that can feel restrictive.
