Accelerated by a pandemic, global conflict and rapid technological change, extremist ideas are becoming more widespread: QAnon proponents run for U.S. Congress, neo-fascists win elections in Europe and hyper-partisan commentators spread dangerous myths to millions online. Julia Ebner is a researcher specialising in far-right extremism, reciprocal radicalisation, conspiracy myths and terrorism prevention. Her new book is Going Mainstream: How Extremists Are Taking Over. She joins our host Carl Miller, Research Director of the Centre for the Analysis of Social Media at the think tank Demos, to talk about it.  We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be.  Send us an email or voice note with your thoughts to podcasts@intelligencesquared.com or Tweet us @intelligence2.  And if you’d like to support our mission to foster honest debate and compelling conversations, as well as ad-free podcasts, exclusive bonus content, early access and much more, become a supporter of Intelligence Squared.
