Hateful and violent extremism has always existed. In healthy societies, these ideologies are relegated to the margins, with most people rejecting the hate-filled, conspiratorial and violent ideas and tactics promoted by extremists.

Instead, in this country in recent years, extreme ideologies have been mainstreamed and normalized at an alarming pace. This is due in large part to the dismayingly large numbers of elected officials and other high-profile influencers who traffic in conspiracies and hate, and to the even larger numbers who remain silent. It is also caused by online ecosystems that traffic in misinformation and hate with unprecedented reach. This trend was blatantly exemplified in the lead up to, during and in the aftermath of the Jan 6, 2021, attack on the U.S. Capitol.

Today, conspiratorial and extremist beliefs on topics as wide-ranging as elections, COVID spread, and immigration and educational priorities – beliefs which are often rife with antisemitism, racism and other forms of bias – are spread by political leaders, candidates for elected office and influential media personalities. Polls show that millions of Americans who believe baseless conspiracies about the 2020 presidential election also believe that political violence is justified to overturn those election results. Recent surveys also show that Great Replacement Theory and QAnon are driving beliefs within this group.

A Whole-of-Society Policy Approach

ADL advocates for a whole-of-society policy approach to fight hate and extremism and counter the threat these pose to marginalized communities and our democracy. We are engaging in federal civil rights litigation on behalf of the District of Columbia against the Proud Boys, Oath Keepers and individuals affiliated with them for their role in the January 6 attack.

We are forming coalitions across faiths, political divides and regions to track, disclose and combat political violence. Along with our partner the National Urban League, we launched Project Code, a new hub to bring together cross-sector partners ranging from civil rights organizations to democracy protection and voting rights organizations to gun violence prevention organizations and more to break down silos and connect our sectors as we combat political violence.
