Distort, post, repeat: Laundering antisemitism on "cliquey networks" during COVID-19.

Today, in the age of the internet, during recent epidemics such as H1N1, Ebola and Covid-19, it is striking to see how old accusatory scripts are circulated and perpetuated via social media, which serve as new channels for discrimination and blame directed at traditional figures who have been scapegoated at different moments in the history of European epidemics.
