We are looking at right wing terrorists and activists the wrong way, IMHO.
Perhaps we can consider them as anger junkies - they need a fix of anger-inducing speech to fill an emotional void.
We can moderate their behavior by looking at their emotional reactions to external stimuli, especially false, albeit inflammatory, statements from right wing media.
Animal and human bodies react to perceived threats with several documented changes.

When humans have an emotional lack in their lives, some fill that void with drugs and artificial stimuli that create increased metabolic activity.
A person with no hope can be stimulated to feeling strong and angry about a person or institution with inflammatory rhetoric whether the speech is false or true. Sometimes groups of people react to anger stimulating rhetoric with violent actions. They are impervious to logic or rationality while in that state.
Unscrupulous actors can create mobs of angry and physiologically stimulated people. The mob can be directed in whatever direction the actor chooses.
It is likely that actors like Putin and trump use that physiologic response to create division and chaos in the United States of America. They use lies and falsehoods to create anger and violence in their followers.
The goal is to profit financially from the chaos and division they create. It seems they play the emotions of marginalized people like a violin.
Our goal should be to prevent falsehoods from airing on broadcast media. When people hear fewer anger inducing lies, they are less likely to use violence.
We created the FCC Fairness Doctrine in 1949 to prevent lies on broadcast media platforms but we canceled it in 1987. We should restore the Fairness Doctrine.
It will help by reducing the volume of anger inducing falsehoods in FOX and other broadcast networks. Social media can ban groups which post falsehoods.
