I read a goodarticle this morning.

Since the attacks of Sept. 11, 2001, and the rise of the Islamic State, researchers have intensively studied what makes someone a terrorist and how people become radicalized. Arie Kruglanski, a research psychologist at the University of Maryland, has found that although the subject matter of their extremism may be different, the way in which neo-Nazis, the Ku Klux Klan and members of the Islamic State evolve from merely disgruntled to violently angry is the same.

For radicalization to occur, there are three necessary ingredients, according to Kruglanski's research. The first is the universal need to live a worthwhile life — to have significance. People usually satisfy this need through socially accepted means, "like working hard, having families, other kinds of achievements," Kruglanski said. Radicals instead tend to place significance on their gender, religion or race.

The second is "the narrative," which gives someone permission to use violence. Kruglanski said the narrative is usually that there is an enemy attacking your group, and the radical must fight to gain or maintain respect, honor or glory.

The third necessary component is the community, or the network of people who validate the narrative and the violence.

There's a lot more in the article. Basically, the big thing that has changed recently is the 3rd component. You-know-who is making hate OK, and that's causing a tipping point.
