Abstract
This article analyses the online response to the Islamist extremist Manchester synagogue terrorist attack – the first antisemitic murder in the UK in decades – and highlights how antisemitism has become increasingly normalised across digital platforms. It explores how the attack triggered a surge of antisemitic content on X (formerly Twitter) including conspiracy theories, justifications of the attack and glorification of violence. The piece also examines how extremist actors across ideological lines exploited the tragedy to advance both antisemitic and anti-Muslim narratives. Drawing on ISD’s data, the article underscores the urgent need for a comprehensive approach to counter antisemitism and extremism in the UK, rooted in the overlap between online harms and offline violence.
