Back when it was first gaining traction in the 1990s, the anti-vaccination movement was largely considered a far-left thing, attracting believers ranging from barter-fair hippies to New Age gurus and their followers to “holistic medicine” practitioners. And it largely remained that way … until 2020 and the arrival of the COVID-19 pandemic.

As this Sunday’s “Defeat the Mandates” march in Washington, D.C., however, showed us, there’s no longer anything even remotely left-wing about the movement. Populated with Proud Boys and “Patriot” militiamen, QAnoners and other Alex Jones-style conspiracists who blithely indulge in Holocaust relativism and other barely disguised antisemitism, and ex-hippies who now spout right-wing propaganda—many of them, including speakers, encouraging and threatening violence—the crowd at the National Mall manifested the reality that “anti-vaxxers” now constitute a full-fledged far-right movement, and a potentially violent one at that.
