A significant body of illustrative literature within political communication revolves around the constructive political virtues and blighting social and democratic consequences of political anger. For the most part, studies have focused in identifying the primary causes and antecedents of political anger. However, within the context of social media, fewer efforts have been devoted to clarifying how and what infuriates people about politics. Does social media news use relate to increased or reduced levels of political anger? Do political homophilic networks explain political anger? And to what extent political homophilic networks influence the potential effect of social media news use on citizens political anger levels – moderating effect? Results drawing on a two wave U.S. survey dataset show that frequency of social media news use alone has no direct effect over people’s increased political anger, whereas interacting in homophilic discussion and information networks on social media positively predicts anger. Furthermore, the relationship between social media news use and political anger is contingent upon online and social media political homophily. For those who report low levels of social media political homophily, greater exposure to social media news largely decreases their political anger.  Limitations and steps for future research are discussed in the manuscript.
