Incels. Anti Vaxxers. Conspiracy theorists. Neo-Nazis. Once, these groups all belonged on the fringes of the political spectrum.

Today, accelerated by a pandemic, global conflict and rapid technological change, their ideas are becoming more widespread: QAnon proponents run for U.S.

Congress, neo-fascists win elections in Europe, and celebrity influencers spread dangerous myths to millions.

Going Mainstream asks the question: What is happening here?Going undercover online and in person, UK counter-extremism expert Julia Ebner reveals how, united by a shared sense of grievance and scepticism about institutions, radicalised individuals are influencing the mainstream as never before.

She explores why outlandish ideas have taken hold and disinformation is spreading faster than ever. And she speaks to the activists and educators who are fighting to turn the tide. Going Mainstream is a dispatch from the darkest front of the culture wars, and a vital wake-up call.
