This paper examines online expressions of rivalry and hate speech in relation to antisemitic discourses in Dutch professional men’s football (soccer), with specific attention devoted to how this has developed within the context of the COVID-19 pandemic. This study analyses football-related antisemitic discourses in the Dutch-speaking Twittersphere between 2018 and 2021. Assuming that during the ongoing COVID-19 pandemic fan activity has moved increasingly toward the online domain, we specifically examine whether and how the past pandemic years have influenced football-related antisemitic discourses on Twitter. Tweets were scraped using the Twitter application programming interface and 4CAT (a capture and analysis Toolkit), producing a dataset of 7,917 unique posts. The authors performed thematic analysis of the Tweets and a selection of the Tweets was analyzed in depth using narrative digital discourse analysis. The findings show how these Tweets, while seemingly targeted exclusively at football opponents, contribute to wider exclusionary discourse in football and society that may have become more aggravated during the COVID-19 pandemic.
