Heteronormativity
Michael Warner made the word "heteronormativity" popular in 1991 in one of the first books on queer theory. It came from Gayle Rubin's idea of the "sex/gender system" and Adrienne Rich's idea of "compulsory heterosexuality." According to Samuel A. Chambers, heteronormativity shows what societies expect, demand, and allow when they consider relations between men and women to be the only normal ones.
