During the first few months of the pandemic, a broad movement coalesced online. At the most extreme end were outright Covid deniers, those who believed that the virus didn’t exist and the pandemic had been fabricated. At the other were Covid sceptics or anti-lockdowners, those who thought that the numbers were exaggerated or that the government had an ulterior motive for restricting freedoms. Over the past year, these views have attracted more and more adherents. Occasionally, the most extreme activists have taken direct action: setting fire to 5G masts which they suspected of spreading the virus, entering Covid wards and attempting to remove relatives, visiting hospitals to film empty corridors and posting them as “evidence” that the public is being lied to about the numbers of sick and dying.
