Fact check: Does the anti-deformation league include the political protests in their data for which political party is more violent?

Checked on October 22, 2025

Executive Summary

The Anti-Defamation League’s public tools and reports focus on hate, extremism, antisemitism, and terrorism rather than tallying political-party violence in the way electoral analysts might compare parties; ADL materials do not clearly state that political protests are coded as “which political party is more violent.” ADL products like the H.E.A.T. Map and Center on Extremism reports document extremist incidents, murders, and hate-activity patterns, and researchers outside ADL report broader trends about right‑wing extremist violence, but none of the available ADL descriptions claim a party‑comparative protest violence metric [1] [2] [3].

1. Why this question matters — Protest data vs. extremist incident data

Understanding whether ADL includes political protests in a party‑violence comparison matters because protests and extremist incidents are different phenomena with distinct methodologies for counting and interpretation. ADL’s H.E.A.T. Map and related Center on Extremism outputs catalogue hate, extremism, antisemitism, and terrorism incidents, focusing on extremist-related activities and murders rather than partisan protest participation rates or cross‑party comparative violence metrics [1] [2]. External researchers citing patterns of right‑wing lethal violence draw on varied datasets — government reports and academic compilations — that differ methodologically from incident-mapping efforts centered on hate and extremist ideologies [4].

2. What ADL’s public descriptions actually say about their scope

ADL’s materials emphasize documenting extremist ideologies, hate incidents, and terrorism-related plots and murders, and describe methodologies for identifying hate groups and antisemitic incidents; they do not provide explicit language that they categorize protest events as indicators of a political party’s overall violence. The H.E.A.T. Map is described as tracking hate and extremism, while Center on Extremism reports analyze murders and extremist perpetrators — these documents frame the dataset around ideology-driven harm rather than partisan protest tallies [1] [2] [3].

3. Independent research paints a related but separate picture

Academic and investigative work cited in the materials finds that right‑wing extremist violence has been more frequent and deadlier in recent years, based on compilations that include government and academic datasets; these findings are framed as analyses of extremist violence, not protest participation or party-level violence comparisons. The research by Jipson and Becker referenced in the supplied analyses argues right‑wing extremist incidents outnumber left‑wing ones, but it relies on datasets and methodologies distinct from ADL’s incident mapping, underscoring that multiple data sources converge on similar risk patterns while remaining methodologically separate [4].

4. Ambiguities in methodological descriptions create room for misinterpretation

ADL’s methodological write‑ups on antisemitic incident reporting and on defining hate groups emphasize public, on‑the‑ground activity and organizational indicators, but they stop short of affirming that political rallies or protests are systematically coded as partisan violence in a party‑comparison metric. The Southern Poverty Law Center’s methodology discussions included in the material also highlight how organizations are categorized based on statements and activities, which illustrates that counting depends heavily on definitions; this ambiguity makes it easy for outside observers to conflate extremist incident tallies with broad party‑violence claims [5] [3].

5. Different stakeholders use similar data for different narratives

ADL’s incidents-focused outputs and external research are used by various actors to support divergent narratives: some policymakers and commentators frame right‑wing extremism as the primary lethal threat, while others assert leftist groups drive protest violence. The underlying facts in the referenced sources show ADL reports document more murders by right‑wing extremists in specific years, and independent research similarly reports more frequent deadly right‑wing attacks, but none of the sources present a direct, ADL‑produced head‑to‑head party violence scoreboard derived from protest-event coding [2] [4].

6. What the evidence supports and what it does not

The evidence supplied supports the factual claim that ADL records and reports focus on extremist and hate-related incidents and that recent analyses find higher lethality among right‑wing extremists; it does not support the claim that ADL explicitly includes political protest events in a metric to declare which political party is more violent. Absent explicit methodological statements from ADL that protests are coded by party affiliation and counted toward a comparative party‑violence figure, using ADL outputs to claim a definitive party‑level violence ranking is not supported by the documented materials [1] [2] [4].

7. Bottom line and what to watch next

The bottom line is that ADL’s public datasets and reports document extremist activity and hate incidents and have been used alongside academic datasets showing more frequent lethal right‑wing extremist attacks, but they do not advertise a direct party‑comparison of protest violence; consumers of these reports should distinguish between extremist incident counts and partisan protest tallies. For definitive party‑comparative analyses, look for studies that explicitly define and code protest events by party affiliation and provide transparent methodology; until such data is produced and published, attributing a party‑level violence metric to ADL’s existing products is not supported by the materials presented [1] [3] [4].
