Actually, right wing violence has been found in a study to be worse that left wing.
Following the 9/11 attacks, there were large increases in Islamist terrorism driven especially by al-Qaeda, ISIS, and their affiliates. More recently, we have seen an upsurge in right-wing political extremism in countries around the world. Despite the ...

Across both datasets, we find that radical acts perpetrated by individuals associated with left-wing causes are less likely to be violent. In the United States, we find no difference between the level of violence perpetrated by right-wing and Islamist extremists. However, differences in violence emerge on the global level, with Islamist extremists being more likely than right-wing extremists to engage in more violent acts.
LEFT-WING VERSUS RIGHT-WING EXTREMISM
Of these three ideologies, most prior research has contrasted those committed to right-wing and left-wing causes. Much of this research suggests that compared to left-wing extremists, right-wing extremists may be more likely to engage in politically motivated violence. In comparison to left-wing supporters, right-wing individuals are more often characterized by closed-mindedness and dogmatism (
9) and a heightened need for order, structure, and cognitive closure (
5). Because such characteristics have been found to increase in-group bias and lead to greater out-group hostility (
10), violence for a cause may be more likely among proponents of right-wing ideologies. In contrast, in comparison to their right-wing counterparts, left-wing individuals score higher on openness to new experiences, cognitive complexity, and tolerance of uncertainty (
5). They are also less likely to support social dominance (
11), which could lead to their overall lower likelihood to use violence against adversaries. In line with this reasoning, some studies have demonstrated an empathy gap between liberal and conservative individuals (
12). Finally, according to various conceptualizations and operationalizations of right-wing authoritarianism (RWA;
13–
15), aggressive tendencies constitute an inherent component of this construct, with people high in RWA being more hostile toward others who violate norms than those low in RWA. A recent meta-analysis supported this conclusion, revealing a positive relationship between right-wing ideology and aggressive attitudes and behaviors (
16). However, the study did not focus solely on politicized contexts and included only milder forms of aggression.
Militant, nationalistic, white supremacist violent extremism has increased in the United States. In fact, the number of far-right attacks continues to outpace all other types of terrorism and domestic violent extremism.

Militant, nationalistic, white supremacist violent extremism has increased in the United States. In fact, the number of far-right attacks continues to outpace all other types of terrorism and domestic violent extremism. Since 1990, far-right extremists have committed far more ideologically motivated homicides than far-left or radical Islamist extremists, including 227 events that took more than 520 lives.
[1] In this same period, far-left extremists committed 42 ideologically motivated attacks that took 78 lives.
[2] A recent threat assessment by the U.S. Department of Homeland Security concluded that domestic violent extremists are an acute threat and highlighted a probability that COVID-19 pandemic-related stressors, long-standing ideological grievances related to immigration, and narratives surrounding electoral fraud will continue to serve as a justification for violent actions.
