In an analysis of sports fans activism and theoretical approaches to understand experiences of mediatized political play, we address groups of activists who protest using fan resources and repertoires. We focus on some episodes of protests performed by casual sports fans against the then-acting Brazilian president Michel Temer during the 2016 Rio Olympic Games. We also further discuss the category of fan when applied to sports and political fandoms, considering the disputes and competition background for which they are not only fans but also rooters.
