Here is an interesting look at some research about terrorists of all flavors and the common threads in the cases. Of course it is not a definitive answer to all the problems of the world, but it is some relevant information. Don't let your TDS get in the way, it's only the first sentence. That stands for Trump Devotion Syndrome doesn't it?
“How do we stop these people?” the president says, referring to immigrants and refugees crossing the southern U.S. border. “Shoot them,” a voice calls from the crowd. And the president chuckles.
Elsewhere, a man watches as a website he built becomes a bastion of fringe movements with violent rhetoric — a cheering section for mass shootings, where murderers are lionized as heroes.
And in Texas, a lone-wolf shooter posts an anti-immigrant screed online before opening fire at a Walmart.
Did the first two things directly lead to the third? It’s impossible to say. But social scientists say there is evidence to suggest that they’re all linked. As research into terrorism and rare types of violent crimes has become more data-driven, it’s begun to show that the people we call “lone wolves” aren’t. Like the El Paso shooter, they may be isolated in their schools or physical communities, and they don’t have networks of co-conspirators helping to plan attacks. But behind these apparent loners is a sense of community and of participating in a movement. They’ve adopted new norms. They’ve had those norms reinforced. And then they act.
