Also, how 'normality' is established in language. Do the words we use-and don't use-reinforce dominant cultural norms?

Eviatar Zerubavel, Distinguished Professor of Sociology at Rutgers University, explores the word choices we make every day, without even realizing it, and exposes the subtly encoded ways we talk about race, gender, sexual orientation and more.
