While right-wing organizing and militia activity has temporarily abated amid the crackdown on groups and individuals connected to the Capitol riot, these networks — bolstered during reopen rallies throughout 2020 — are likely to reactivate when the next politically salient moment arrives. The ‘anti-vax’ movement could serve as such a catalyst, as anti-vaccine activists are already a growing force at reopen demonstrations (New York Times, 4 May 2020), and have increasingly found common cause with right-wing anti-lockdown demonstrators as they shift their focus to the vaccination rollout (New York Times, 6 February 2021). Many of these demonstrators are new to the ‘anti-vax’ movement, joining as a reaction to the coronavirus pandemic and what they perceive as an attack on civil liberties mounted by the government in response to the health crisis (New York Times, 6 February 2021). Building on the reopen organizing that began in early 2020, organized opposition to the vaccine rollout in early 2021 could serve as an important nexus allowing militias, militant street groups, and other right-wing social movements to develop additional networks for future mobilization.
