Populism has gained significant attention recently, yet there is less understanding of strategies to confront it. While antipopulism is argued to be depolarizing, based on civility, calmness, and knowledge, populism is portrayed as polarizing, using emotional and irrational language. However, we know little about the ways through which antipopulists present themselves as an antithesis of populism and how these identities are presented stylistically. This study thus examines the content of the populism/antipopulism divide in the messages of antipopulist actors and their association with specific communication styles on Facebook and Instagram in the Czech Republic.
