We perform gender throughout our online lives: Instagram selfies, dating profiles, and TikToks, are just a few genres in which we craft different identities according to the rules of the platform. This course examines both influencers and everyday social media users who use their gendered and sexual bodies to launch cultural trends and make political statements. Moving between US and international contexts, we see how dance challenges, feminist activists, fashion blogs, and misogynistic Reddits reimagine gender and sexuality online to build micro-cultures that are distinctly digital.
