This document discusses different perspectives on defining gender and feminism. It contrasts social constructionist views that gender is influenced by society versus biological essentialist views that biology determines gender characteristics. It also summarizes theories by Deborah Tannen that masculinity is the unmarked norm in language while femininity is marked, and by West and Zimmerman that gender is something we "do" through our behaviors that are assessed against norms. West and Zimmerman also distinguish between sex categorization and doing gender as separate concepts.
